[solved] Bug? Synchronizising different profiles

Hi,
yes, I have read

https://faqs.ankiweb.net/synchronizing-multiple-profiles.html.

Different persons are using my desktop-Anki. They all have their own profile and their own Anki-account.

There is one profile which has only one deck with 40 cards only, but synchronizising this with the correct account belonging to this person inside the correct profile seems to send all the cards of the other profiles too.

Is individual synchronizing dependend on profile imposible?

Best regards

Are you sure you are using different emails for each profile?

I could solve the problem by deleting Anki and installing the newest Version.
