I use WP plugin H5P Version 1.15.6.
WP admin is on FF, I tested the Memory game on front end on FF, Windows Chrome and Android Chrome. There is always the same issue.
I made two memory games, these issues are in both games.
When I test via Preview in WP admin, everything is OK, there is a "Description", but when I start the game in the browser, that "Description" does not exist when the images match. Please see the picture on https://prnt.sc/29oFLg1lUo_T
