Bug Fixturebuilder V3.11.0

Hello Fellow Hog users
I currently expirience some problems with the fixture builder

Roadhog4 running software version 3.11.0 connected to a rig by artnet. The rig consists of a few Robe DL7S in mode 1. The fixtureprofile in the library has a few wrong values for gobowheel 2 and the animation wheel which I would like to change. When I have made the corrections and I want to build the new profile the builder returns an task error with no description of the actual problem. I contacted my local distributor for advice on this one, he told me to make an export of the changed library and try to import the new fixture from there which, unfortunately, does not work. Any thoughts on this?

Thanks in advance
