The block "is mySprite hitting wall left" won't render or appear in the menu in tutorials

I’ve been trying to make a platform game tutorial, but I’ve hit a snag. To keep the player from being able to jump in mid air, which would be a game breaker, I’m only letting the game character jump if it’s on a platform. For this, I’d like to use the block “is mySprite hitting wall left” (“left” would be swapped to “bottom” in my case) as a criterium in an if-then block, which works fine, but this block won’t render in the tutorial, and the block doesn’t appear on the menu for the user. Is there another way to achieve the same result, or is there a way to get this block to appear in tutorials?
