Circle with a red line through it in develop mode

[DornickDesigns]

Help!  This circle with a red line through it showed up in Lightroom a couple days ago and I have no idea what it is, or how to make it go away!  Thank you!

Does a pop-up show up explaining what it is if you hover your mouse cursor over it.  I have NEVER seen that symbol so I am vary interested to find out what it is.

I'm not familiar with that symbol either. But I wonder if it has anything to do  with the fact that the image is not in the current process version. Just a thought.
