Some key modifications don't work inside Secure Folder

Hi, would there be an easy fix for some modifications not working when I type inside the Secure Folder (on a Moto G)? I noticed that the issue is related to specific positions. There are 3 spots where I put "@", "!" and "(". At first, I thought the problem was related to the symbols, but even when I replace them with letters, those spots still don't work. I have the same modifications inside the secure folder and outside it (a copy-paste) and it works as expected when I'm outside of the Secure Folder. I can paste my whole code if it helps. Thanks for finally implementing this user-friendly feature!
