Clones Not Deleting Themselves

So, I'm working on a project that uses clones as items to dodge, which I am using the game "UNDERTALE" by Toby Fox as a reference. For the fifth attack that I'm working on, the clones of neither of the 2 different attacking sprites delete themselves, and just remain on the screen until I press the stop button.

Any way to fix?

Sorry that it's so zoomed out, and thanks for helping.

It'd be easier for us to test with a link to the project... but, are you 100% sure that AttackNumber=5 ever actually happens? Maybe put a PAUSE ALL block inside that IF to make sure.

...or try a countdown until 2020 script pic block
