Hi @kimKV67A ,
Sorry to hear that you're having trouble.
Could you please share more information about the issue? Screenshots and videos could help us to understand your problem.
By the way, if your library has been updated with new version, you need to go to schematic or 2D PCB editor > Library tab > Libraries > click Update design found all libraries used in design.
Then the previous added part from the old library will be updated, and view in 3D PCB will get the latest 3D model and footprint. Otherwise it will still use the old version of library.
Not sure whether it's your case, just share with you to be aware of it.
Looking forward to hearing from you.
Regards,
Helen
