I have had this happen .This is how to avoid it. All your comps should be in only ONE AE project.
1. Choose clip in PrP and Replace with AE Composition. (DL)
This opens up AE
2. Choose second clip and Replace with AE Composition. (DL)
The trick is when you return to editing this project (ie the next day),
select the AE DL clip on the PrP timeline and choose Edit Original. This will open the existing AE project with all your comps. If you make the mistake of selecting a new clip and Replace with AE Composition, now you have 2 AE project files with similarly numbered comps. This is where things get screwed up.
Once an AE Project exists, you should open it FIRST by highlighting an existing AE DL clip in Prp and Edit Original.
