I had the same problem. What is going wrong here is obvious: The CAM does not properly recognize which packs are installed.
What I THINK may be happening behind the scenes is, that in the new version (former) content packs are stored in a diffent folder than before was the case. (At least that is what I saw when I started looking for the folder where packs could be storred.) So CAM is sometimes confused where pack are, whether pack can be found in old and new folders, and may not be looking in the list of installed apps, software and packs. Of course it does not make sense to rely on the latter when the pack cannot be found by PD.
Uninstalling and reinstalling sometimes did the trick for me. But I would assume that the inventory keeping in CAM old between new places, is not completely in order yet.
