You share a boot partition between all the distros?  Yeah,
grub2-mkconfig as it stands really has no way of figuring out which
one's which in that case.

You don't strictly have to edit/rewrite grub2-mkconfig, as long as
Fedora is the only distro messing with GRUB.  Fedora does not rerun
grub2-mkconfig on update, the grub2.cfg is patched by grubby.  If you
go in and fix /boot/grub2/grub.cfg, it should stay.  (This is *not*
the case for most other distros, however.)

If you do want to hack on grub2-mkconfig, it runs scripts located in
/etc/grub.d/ to make up the configuration.  See /etc/grub.d/README for
details.  Note that changes there could get clobbered on grub2
updates, so be careful.
