All BAT are gone after connecting to Gemini Wallet

Briefly describe your issue:
I’ve allready collected arround 15 BAT (i know, it’s not that much, but honest work). So I wanted to connect my BAT to a Gemini Account. After everything got set up, my balance changed to zero. So all my Tokens are gone. I found no instructions or solutions how to get my BATs back.
