How do I fix Caps Lock detection?

I'm working on a crossword puzzle, in the game I have a visual keyboard that interacts with the key I press and shows an animation, but when I use an uppercase the animation doesn't work, I know that the keyboard parameters warn me about possible Num Lock issues maybe is the same with Caps Lock? but I'm not sure how to fix this.

Animation name is case sensitive if I am not mistakenly remember.

I have old crossword example too: dropbox.com/s/2ymk52xp0inxk7k/crossword_alextro.capx

I was trying with options like case sensitive or ignore case but i still have the same problem.

I was thinking maybe a way to know if the cap lock is on, maybe i can pause the game until the player press cap lock until is off because i dont undertand why the game doesnt work well with a simple condition of Press button
