Cargo station can't be replaced, unless you press F.

In the video you see I grab one station and am able to replace the loose station with the unit station. BUT, when I grab a different unit station that is also orientated differently. I am unable to replace the loose station until I press F.

video won't play for me

Video plays for me.

Ok, it works now. I think this is the same issue as 'Collission with Flat balancer' when balancer rotated. The issue is there for a lot of buildings that can't be replaced, rotated, or flipped.
