Bug when removing "special" bar line

Whenever I remove a “special” bar line (double bar lines, repeats ect.) there appears one of those red flags with the time signature in them over the measure that can’t be removed (see attachment). The only way to get rid of it is to delete the time signature for the whole piece and then put the time signature in again.

You can, of course hide the red flags via the View > Signposts menu.

WoodwindBlues, I think you must be removing the barline by replacing it with a single barline: don’t do that. Just delete the barline, and the expected single barline will be left behind, and no signpost.
