Yet Another Post for Token Marker Numbers not Working

I apologize if this has been covered elsewhere - I did read a few other posts regarding display of numbers on token markers. Using an iMac with Firefox, I try to hover over any of the color circle token markers (in the selection rollout menu), type a number, the mouse pointer disappears, and a number or colored circle doesn't appears over the token. I can click on the colored circle and it appears, but to just hover over the appropriate circle and type a number does nothing. Please help, I like this feature and have successfully used it before on a Windows platform PC. NOTE:  My buddy can, on his Windows based PC, put numbers up on the same game that I am attempting to add the numbers

Don't understand it but tonight I went into my game and saw a few tokens with dots and numbers on them.  I removed them and thought maybe I should try again to assign numbered, colored dots to tokens and this time it worked. I did nothing different. If a developer or moderator fixed my issue, thank you! I didn't receive any notification that anyone was working on it, but as I stated it now seems to be working on my macOS platform. Thank you again kindly.
