Thank you! I am quite new to using zotero and obsidian. I thought I had a bib file, but now it seems I have an autogenerated json file instead.
I can find the reference in it. The reference is there just once. That part of the file looks like this. I assume it must be working, as when I reference to this from another vault everything is fine.
