calc: badge number on tab label?

I did an all sheets search from a known tab. I don’t know if that has anything to do with my issue or not, though. It was the first time I used that feature.

Then I noticed that there appeared a number “1” inside a badge, attached to the beginning of a different tab’s name. It wasn’t the same tab in which I conducted my all sheets search.

What is this number? Is there a way to remove it?

I went back to the original tab where I did the all sheets search from, and ensured the find command was not still activated by noting if the find field was showing. It wasn’t.

Thanks,
