If you do not get a good answer here for your problem then you might want to head over to the bug tracker.
Disclaimer: Below is an answer to a question you did not yet ask. I read your question wrong originally. But i leave my answer here as it could be useful to you anyways.
The libraries have been reorganized for version 5. This has two consequences:
- old projects will not render correctly if you do not provide the old 3d model library.
- your library setup might be wonky without user interaction. This is because your personal global footprint library table is not updated. (will still point to version 4 on demand online libs) Symbol and 3d model libs will however use version 5 libs (there was no symbol library table in v4)
More details see: I had KiCad 4 installed previosly. Now i updated to v5. Now i have some problems with the library setup
