Layer not showing in crossword!

So I am having issues with my crossword not showing one of the layers in storyline. It will show the Clue layer and the "Try again" layer, but the "You got it!" layer just won't show. I have 2 slides, one with the variable references to each word so I could see if there were any issues with the letters for each variable, but there are none. I have also tried re-making the layers and reordering the layers but nothing. I have shown it to my team and even they are baffled by this. I'm hoping that the wizards in E-learning heroes can find a way.
I am also concerned that the learner can type more than one letter into the text-entry field and not be able to see that there is more than one letter, which will cause an error in the variables,... is there a way to cap the number of letters inputted in? 

I cannot take credit for the original file as it was produced by another e-learning Hero, I have just edited to suit my needs.

When previewing the file, I had to put a temporary slide in to show all the variable references, so to get to it, I also put in a temporary 'next' button. The answers are in the notes.
