I suspect I know why this happened.

Do you have the "sdubby" or "systemd-boot-unsigned" package installed (which 
brings in sdubby)?

The sdubby package installs an /etc/kernel/install.conf that tells the 
kernel-install script that runs in the kernel-core %post to install kernels and 
initrds in /boot/efi/$MACHINE_ID/.  (Where $MACHINE_ID is from the contents of 
/etc/machine-id).

This is something that systemd-boot uses, and I'm not sure why it happens, but 
some dependency seems to pull that package in for some people.

Backing it out simply means you need to uninstall the sdubby package and re-run 
the kernel-install command, or more simply, reinstall the kernel-core package. 
Once that's done, it will do the normal GRUB2 boot method of putting files into 
/boot/ and blscfg entries in /boot/loader/entries/.
