B5 V3 not loading previous versions settings properly

[Leo D]

I made a track using UVI Workstation v3.0.25, and B5 v2.5.1, in Logic Pro X.

Then I upgraded to UVI Workstation 3.1.4 and B5 v3, and when I open my Logic File, the organ sound is completely different.

I tried to revert to my previous version of UVI Workstation and B5, but it did not solve the problem. The sound is different.

And it's not slightly different. It's VERY different. Like the drawbar settings and the rotary speaker are not the same.

Anyone can help?

Many thanx.
