Startup "Use current pages" loads all Tabs twice

I have experienced this in Chrome (and can’t remember who I solved it). I have 12 pinned tabs and in settings I selected “open a specific set of pages” / “Use current pages”. When I start Brave, all tabs appear 2 x - the first set as pinned, then a 2nd set not pinned.

Wonder what I am doing wrong.

Apart from this: Love this BRAVE browser!

That’s certainly very strange. Testing on my end (macOS), I only get once copy of the site. Would you mind sharing the list of specific sites as they appear in your Settings?
