vst transit : not everything is synced

Hi guys,

a quick question.

I have setup a vst transit with my partner (also cubase owner).
now if I make a new project and then sync it.
the first time he wants to open it, no download button available but also if he opens the project only Steinberg vst is synced.
the rest of the vst plugins are not synced?

normal or not?

thx
Didier
