Red dot under the mask symbol
I am using version 12.3 of LrC. On one of my recently processed photos I am getting a red dot under the Mask tool symbol. Normally there is a white (or light gray) dot under the tool symbols like "Healing", "Crop" or "Edit" indicating that some modifications were done with that tool, but in some cases I'm seeing a red dot. Does anyone know what that's about. I have revisited that tool and made sure that modifications were complete. So, I don't know what may be causing that. Thanks for your help.
