Migrate local translation memories to cloud from Studio 2022

In Studio 2022, I want to migrate local translation memories to cloud, but I cannot finish the process because the "Language processing rules" tab asks me to enter something, but
- I do not have the Default language processing rules button ( !! ) why?
- I can only push a button to Add language processing rules; this leads me to the language cloud platform where I am asked to select language processing rules, which I do but then nothing happens and
I cannot go back to the "Migrate local translation memories" window in Studio to finalize the migration.

I am following the instructions of a training video (https://www.trados.com/resources/getting-started-with-cloud-capabilities/) but this problem is not dealt with. Can someone help me?

Thanks, Valeria
