Would you like to create a matching exercise where all the matching items (pairs) are either visible (="Matching JMemori") or hidden?

JMemori cannot have a ReadingText.

If you are creating a JMemori exercise with pictures you should not use an apostrophe in the title / subtitle / instructions if you have entered images into the JMatch' right column "Right jumbled Items"; to avoid this, put your images only into the left column (if you make an image-text matching exercise).
