Assets missing from library

[GerbenVanErkelens]

Since this morning a few asset groups seem to be missing in my shared Creative Cloud Library. Right now I only see the type graphics, motion templates etc. All colours, XD components, Typography styles ar MIA. I already checked the archive and deleted files but they're not located in there either. 

Are there any copies on my local device where I can check if they're still there? 

I also asked the members I shared the library with if they have the missing files in their deleted files (although I do not think it works that way) which wasn't the case.

Any ideas?
