Spell check being activated in insert mode

I have a really strange issue, when typing caus it activates a spell check and either corrects it or gives an error saying it can’t correct it, I suspect the u key somehow triggers ctrl-x and then the s key does the spelling change. I have 9 insert mode bindings but none of them should affect this:


My entire config is located at GitHub - lars-vc/neovim-config
Hope you guys can help because I am really confused

Edit: I am pretty sure that the u key triggers a ctrl-x but I still don’t get why

I fixed this by deleting my plugins folder and reinstalling all of them
