Citing only works sometimes

Rakso97

Hi,
I don't know if I'm doing something wrong or if there is a simple/obvious solution, but sometimes when I am citing with"@...", not all sources get listed. I tried restarting Zotero and Zettlr and copying the cite-key, but I still can't cite some sources.
Does anyone have a clue, what the problem might be or what I can try?
Thanks in advance!

Nevermind, I found out, what the problem was.
I used the group-library in Zotero so that the sources get saved in the Zotero-cloud. The problem is then, that the meta-data is not saved locally, thus the folder that Zettlr accesses to cite is not updated.
So I am back to using my own library without using the Zotero-cloud.
