Bugs in content types

Hello, Since a few weeks or so (I'm not sure), when matching pairs, I don't get the pop-up with the specific text showing up.  I thought it was due to Learning Dash but I am told that is does not have anything to do.  I made so many memory games for my learning language institute...  Can someone assist me?  I deleted the memories and caches of my computer, I started it again.  Thank you for you help.  Elisa

Hello,

Best regards
