Strange symbol on board in PCB Editor

I have a strange symbol that shows in PCB Editor. It looks like a light blue circle with an X in it.

I can't remove it. I should say I don't know how to remove it.

I think I know how it got there.

My project includes a JQ6500 module (a small board that includes some electronics) that requires a resistor across two pins that are on this module, not on my PCB. I made the mistake of including this resistor in my schematic. Of course, when I created the PCB board, that resistor showed up wanting to be placed somewhere. I highlighted it and deleted it as it didn't belong on the board. Only then I went to the schematic and removed it. That was when I noticed the circle with the cross in it.

It doesn't show up in any of the DRC output, so I don't think it will cause a problem, but I'd like to clean it up.
