Using letters for "suport keys" in ftl setup

[Eloxy]

So. is there any issue using for example " i " as a suport letter for ftl? (ctrl+alt+i) like this

I have done it in my setup but for some reason some letters simply wont work. " P " works wonders for example.
Anyone has any experience with this? and yeah i have unbinded all the combos for the letter in wow keybinds

And one more thing, is it any limits to how many keymaps we can have in a single profile in keyclone?
