There is an error in a key place in the Polish language version.

I don't know if this is the right place to mention it, but... There has been a confusing translation error in a basic element of the Looker Studio menu for a long time.

Haha! Nice one!
There are hundreds of similar AI based translations across whole GCP enviroment.
I am using english as polish language version is totally not production ready for 6 years already.
