Command N buggy behaviour

Whenever I press Cmd-N for a new window, the finder bugs out and it looks like a conflict between classic finder new tab and totalfinder trying to add a new window. This didn’t happen before so not sure what changed it.

If I then close the tab, the top tab remains bugged

I have Open folder in tabs instead of new windows disabled in the classic finder preferences and have tried all 1.12 version of TotalFinder. I am on Catalina
