GarageBand pastes wrong region

When I try to copy one region from a track of one project to a different (another file) project the region actually pasted is another one that I used previously in another time, not the one that I'm actually trying to copy.

When I try to do the same within the same project to another track it pastes the intended region just fine.

I already restarted the Mac, changed the name of the track and the region, duplicated the project and nothing has worked.

What else can I try?

Thanks in advance.
