Roll influences the orientation of the band while it goes around the wheels. It causes the twist you describe when configured wrongly. This can happen ether by wrong orientation of bezier points or by high values for the roll field in circular points.
If you share the model I could take a look at the problem as I'm not completely sure what you are trying to do.

The library it self: download complete.zip and overwrite the old one (I recommend deleting it first though).
Flexible parts: nested editing mode, or the part's own session.
https://bricksafe.com/pages/1963maniac - "Didumos Sequential 8 Speed Transmission..." That is my file that I've been working on. The O rings are a little goofy. They are located and wrapped around the 1/2 bushes properly. But, they have flat portions and wrinkles. There are 4 of them. Thanks for taking a look.
