Ok, after just a quick first run on these, my first couple of advices:

1. Make some (more) '2-chords-per-bar' entries, at least the more common ones like IIm7-V7, IV-V etc. Better still would be some common '1-chord-per-beat' too, like you see in some of the longer PG templates for Usertracks making - The less the program needs to chop your audio up, the better.

2. The quickest way to spot potential issues in UT's is by using them in ways you didn't envision them for (let alone intended!), both in terms of concept and chords used.

Just because you can, doesn't mean you should!
