I think this was introduced in F30, and it became the default in F31.
Called snippets. It is no longer necessary to update the grub.cfg file
with snippets enabled, though it is OK to do so.
Yup, found the change URL. I'm sure I read it when it was originally published, but failed to "grok" it's impact.

Assuming you are using efi, and if you go into /boot/efi/EFI/fedora
and run the command
grub2-mkconfig -o grub.cfg
that should fix your issue with kernels in the menu.
Well, not exactly... This one is non-EFI. I actually converted my desktop to EFI and it was VERY painful and took me months to track down weird bugs because it wasn't 100% migrated. I'm glad I did it one (got the T-shirt) but I have no intention of ever doing that again :)
Not sure what is
causing the lack of cleanup, as everything updates correctly here on
F31. Maybe check /etc/default/grub to ensure options are set the way
you want? Perhaps you caught the migration from the old grub2
technique to the snippets technique, and there was cruft left over.
Did you save more kernels in the past, /etc/dnf/dnf.conf?
I updated grub2/grub.cfg but I did it to a temporary file first and diff'ed the differences not finding anything significant. I deleted the extraneous entries in /boot/loader/entries and installed a new kernel in testing (5.5.15) and everything appears OK.
Must have been a migration issue. Not that should make a different but I am booting BIOS with a GPT partition using a 2M "bios_boot" partition.
Thanks,
Richard
