Sorry for the trouble here – as @ncpl points out, this is a known issue, and we’re planning to deliver a fix for our next release.
For now, if you’re stuck try this unseemly workaround 
:
- Use the hotkey to open preferences (Ctrl + comma on Windows)
- On the General tab, click disconnect under Library
- Choose your library again
- Let us know if this works for you
Sorry again for the trouble guys. Please let us know if these steps don’t work for you, as it could be a different issue.
Thanks all!
