Education: Moisture control

Hello fellow members,

hope everyone is well and surviving the winter.

Attached are two photos of my residence. The first shot is of a clean and well maintained bathroom celing vent. Looks may or may not be deceiving…
If you look at the second pic, it is clear that the vent terminates at the exterior wall, however the flapper is hung up and not closing properly allowing conditioned air to exit and warm humid air to enter. Also notice the bottom of the frame is not sealed to the wall.
Will have maintenance look at it. Third floor, tough fix, simple problem.

Whats your point?
