pacman uninstall hook missed kernel with prefix about kesboot HOT 1 OPEN

for successful kernel uninstall, i added 2 parts in main.sh:_remove_efi_hook:
after _strings="${_strings%%/*}" added:

		local _version_backup
		_version_backup="$(echo "$_strings" | cut -d "." -f 1,2)"

and after _final="${_final#(}" added:

		if [ "$_final" == "builduser" ]; then
			_final="${_version_backup}-$(uname -m)"
		fi

i'm unsure thats going wrong, but it looks like the kernel doesn't contain the expected string

now i'm get:

(2/3) Updating EFI variables (remove)...
===> Removed 6.7-x86_64

from kesboot.
