Room always "selected" even when I click away or choose another room

[BingoSF 0]

This just started last night but I have a room that is greyed out as if it is "selected" but I can't get it to stop.  I can select another room (and then they both are grey).  It's probably not that it's "selected" so much as there's some sort of fill (though I have checked fill) that's causing it to always be grey.  Any tips?

Answers often depend on which title (Suite, Pro etc) and version (2018, 2019 etc) you are using.

 

You can help everyone by adding that info to your signature (see below for how to turn them on) by clicking on your user name at the top right of the page, click Account Settings, then Signature on the left.

 

Doing so makes it always available, and keeps others from having to hunt for it.

 

And, turn on signature display too.

For questions like this, attaching the plan file really helps.

This grayed out area sometimes fills in adjacent rooms or spaces if there is not the proper demarcation.  One used to have to use an invisible wall but I'm just returning to use the program after a couple years away.
