Hello, I have the same problem with the list of my publications:

https://bibbase.org/show?bib=https%3A%2F%2Fapi.zotero.org%2Fusers%2F10176%2Fcollections%2FTF8X26N8%2Fitems%3Fkey%3D7qraobRCjdfVup9q5USnsAPd%26format%3Dbibtex%26limit%3D100&msg=embed#

The problem does not seem to be on the Zotero side: here is the bibliography generated from the same library, which is complete: https://www.dropbox.com/s/o0ol1oqwrhxmgjb/My%20Papers.rtf?dl=0

Thanks in advance for your help!

All the best,
Paolo
