DM having a players modules load into session

Not sure if this is the correct Forum section to post this

System: 5e

I logged into a DM hosted session to create a character. As the DM was showing me how to load items from the Library he commented that "other" items were being loaded into his session. I have an Ultimate License and all the books (DMG,PHB,Xanathar, etc and Rob2e stuff), but was logging in "only" as a Player to his hosted session. It appears that my Rob2e items began loading into his session on his end. Is that supposed to happen? I thought that only what the DM opened was what was available.

EDIT: I remember him saying it was the 5e Defier Class from Rob2e.

Any player owned modules will show up in the GM list for approval. However, the GM can only grant or deny access, they can not open or share the material since it’s not installed on their machine.
