Grouped tabs not working

Description of the issue:

I now just have a list of open tabs. I’d like my tabs grouped. I go to settings and appearance and click to enable grouped tabs. I relaunch the browser and… Didn’t work. I try over and over again. I can’t get it back to being grouped. How do I fix this?

This is the new version of Brave, but also tried the October version (88?) And a previous one. Same issue happens on all versions.
