Looking at your minimap (the shape of the visible area of the camera) to me it looks like the Camera does move to the unit that is selected as it should, but the settings of the Camera are different from the usual one.
Have you by any chance used "Pan Camera" or a similar action in you map before? It's possible that this way you have applied different settings to your game Camera and now it's not working as it should.
Well, another reason for this could be, like already mentioned, some different settings in the Data Editor related to the Camera. Try to compare these entries.
Edit: Just saw that you disabled all Camera-related Triggers. Could you tell us what kind of dependencies you are using?
