Just FYI... at this point I would highly, highly recommend not converting old playbooks and instead just create new playbooks.

VERY peculiar issue occurred when I was going through my old playbooks one after the other... I can almost guarantee that it was somehow merging the first two. Then, the third one I looked at was a defensive playbook and it said I had 399 plays selected and 34 formations (there aren't 34 defensive formations available) when it only showed 12 selected formations, and at least two of the original ones I had selected were missing.

Again, I can't stress enough, don't convert an old custom playbook... it will only create additional possible headache for you.
