Tabs that are on different windows don't merge into same window anymore

The issue is when i have a single tab on a separate brave window and try merging it with an existing brave window it doesn’t happen any more . Not sure what is triggering .
I am currently running the version

1.34.80 Chromium: 97.0.4692.71 (Official Build) (64-bit)

I’d be happy to provide any other information required as well.
