While using CBT with TwentyTwentyFive all pattern are locked - in the current theme

After exporting a ZIP with CBT all pattern are locked - in the current running theme. I'm using TwentyTwentyFive.
I'm developing a new site for a client and I'm in that phase the only user and admin of course.

I can duplicate a pattern and give it a new name - that is unlocking it and I can use it - but have to change all instances - that's annoying.
