ZMK keys with modifiers issue with Mac

I got this corne keyboard that works perfectly fine on Windows. The issue is on my Mac, where some keys with modifiers, like (^), behave erratically. I have a symbols layout, and I often have to press the keys repeatedly until they register. However, when I press the symbol key along with Shift, it works instantly. While setting up my layout on ZMK, I noticed the combination of Shift + caret appears as a modifier.

I suspect my Mac is having issues with these keys. I also had a similar problem with the space bar; I set it up to tap for space and hold FN, but it wasn't registering the space. I had to remove the tap-and-hold feature, and now this is affecting how I use the symbols.

EDIT: fixed it by going to accesibility and turning off slow keys
