Didn’t find a definitive solution. I fiddled around based on the Master list link that was provided and it eventually fixed but I’m not sure what did it. Interestingly, I did the same thing on a second blog that had identical issues and it wasn’t fixed until one of the plugins had it’s 2nd “3.1 upgrade” released. Apparently the first try didn’t actually fix the plugin. Also worth noting is that deactivating the plugin didn’t solve the problem. Good luck!
