Duplicate Tag Selections in Focus Tool

I have no idea how these duplicates came to be:

How do I return things to normal?

Use the Tags browser. Select the tag(s) and Delete comes up - on a tablet or PC.

Now on a mobile, because of restricted space you just see a narrow white bar - between the 3 dots and the ‘X’ . That’s the delete function!

EDIT (found the screenshot function on my phone)

@mike - hardly intuitive, would be better included in the 3 dots menu?

Thx much. Know why these pop up?

No idea. It hasn’t happened to me.
