Zotero Group Libraries do not show up in RStudio citation in visual Rmarkdown

Hello,
I'm using the latest RStudio IDE preview (1.4.993-1) on win10 last update, and I'm trying to add a citation from Zotero.

Using Visual RMarkdown, from the citation menu, only my Personal Library is showing up, but the Group Libraries are not there (neither the references included in there)

Here's my Zotero libraries

Do I have to further configure Zotero/Rstudio to have access to them?

Thank you

Just an update. Also a colleague of mine encountered the same problem problem

Confirmed also in Linux (with a different account/user, not me)

For reference, this has been posted also in GitHub
