Placing tags using Auto-Insert Tags - SR1 Trados Studio 2021

Good afternoon,

I've just installed the SR1. I wanted to try "Placing tags using Auto-Insert Tags" but it doesn't work. 

I followed tutorial, enabiling Repair, checking if my TM has more than 1000 units, but anyhow it doesn't work. 

Where could be a problem?

Thanks!
