Factual error: Agent Carter takes the coded message and decodes it, where it starts with coordinates of 53° 72 minutes north, 27° 37 minutes west, and is told that location is in Belarus. Two problems. 1) The minutes value can only be between 0 and 59, so 72 is an impossible value. 2) The location given (ignoring the 72 minutes problem) is in the north Atlantic Ocean, but they were close. Belarus is roughly 53 north and 27 east (not west).
Continuity mistake: Daniel enters the meeting room in the office and places a file and some documents on the desk. In the first shot, he is shown placing the red file on the desk with some other documents placed on top of it. The shot changes to a shot of Daniel, and the other documents placed on top of the file are no longer visible. The red file is still there.
