Barney is holding a gun in his right hand as they begin to drive away. They steer past the Vandamm sign and now Barney is in a different position holding to the top rail of the truck bed and no gun in his hand.
When Barney is in the elevator shaft removing the grate, you can see a screw is still in place at the top of the grate, when the elevator passes Barney the screw is no longer there.
While Jim and Willy are posing as gardeners, they have to subdue two guards. When Jim hits the first guard, the second steps toward him and away from the edge of the walkway. But an instant later, when Willy swings a shovel at his legs, the guard is closer to the edge than when he began, not farther.
The tape recording informing Jim of the mission claims that Carl Vandaam has stolen enough plutonium 240 to manufacture a hydrogen bomb. Plutonium 240 actually inhibits fission in a nuclear weapon. Plutonium 239 is the fissionable material that creates the explosion. Plutonium 240 would be useless in creating a nuclear weapon.
In the briefing, Barney says that the walls of the elevator shafts are covered with grease. That could be an option but the only things that are guaranteed to be coated in grease are the guide rails and the cables, the latter of which he uses to climb which would be incredibly difficult at the very least. In the close ups you can see they aren't actually steel cable but regular 3/4" black 3 strand rope.
When Barney gets on the elevator that services floors 1 through 7, in the time it takes to start up from the first floor and stop at the second floor, Barney has opened the ceiling trap door, worked his way up through the door and closed it. The elapsed time seems very long for an elevator to travel one floor.
When Barney climbs up above the elevator, it can be seen that the elevator moves very, very slowly. It moves much slower than in an ordinary building.

The PH and B locators on the elevators are inconsistent throughout the episode. Sometimes PH is on the left, and sometimes it's on the right.
The PH indicator is always on the left.

Jim's photo of General Castillo is a reuse of a picture of General Dominguez from the pilot. When Rollin later shows up in disguise, he looks nothing like the man in the photo.
When Barney leaves the elevator on the 7th floor, the office number sign shows #708-730 to the right, and #732-760 to the left. Barney goes across the hall and to the right of the elevator and goes into office #704. The same thing happens with the guards on the 2nd floor. The low numbered office is 208, but a guard goes into office #206.
The view out the window of Vandaam's office is obviously a painted backdrop.
The offices 704 and 706 are not errors. The signs starting with 708 and 732 are pointing to offices in the side hallways, not the offices in front of the elevators-704 and 706.
When the Plutonium container is disassembled in the isolation booth, the casing is screwed onto a fixture attached to a conveyor belt. No set screw or other method of locking the container to the fixture is evident. When the first arm comes down to unscrew the top from the casing, because of the diameter of the casing and the top, there would be more friction between those two pieces than between the casing and the fixture it is screwed to. More than likely, the arm that removed the top would really have unscrewed the casing from the base fixture.
Rollin leaves the penthouse after withdrawing his bid, but although the building is locked down, his escape path is not shown, and he is not seen leaving with the others.
When Barney calls Jim, none of the phone buttons are depressed or lit. This indicates the no line was selected and Barney was only talking to himself.
When Barney picks the lock of the doorknob, he uses only one tool (possibly a rake), but uses no tension wrench to apply torque on the barrel inside the lock. Both tools are required to pick such a lock.
