It looks like you're on Fedora and so you have a GRUB modified by them. The official repo does not replect the contents of the uefi-firmware script. Please take this issue up with your distro.

Want: To regenerate config for any reason, but also typically to remove excess Linux kernel version or duplicate Windows entries after partition boot flag or even entire data erasure cleaning.
