Default GRUB boot entry not working.

a regular distribution and an Atomic distribution

What the heck is "atomic" distro lol
Why do people even bother with things that need special care especially if it's something non standard.

Atomic aka Immutable distributions, they're imaged based Linux distributions focused on a containerized workflows, but dual-booting with those doesn't seem to be very well supported as with the warnings that they have limitations when it comes to custom partitioning and dual-booting.

Been doing a bit of searching and try getting a vm to dual-boot a regular and atomic distribution, but couldn't get it to work. Seems the recommended way to dual-boot a regular distribution and an Atomic distribution is to use your UEFI menu which one you want to boot, which would mean you need need a separate efi partition for your Atomic install. This also the Bazzite documentation recommends.

Do you mean you are trying to add the other distribution's kernel entry in the same GRUB config of Fedora? I don't do that. I have separate bootloaders for Fedora Atomic and Arch Linux, and on separate EFI partitions.

So the easiest way to do that is just to use "one-time boot menu" each time and then select from there which one you want to boot. Not sure if "one-time boot menu" can be configure to always show up by default.

What is a "one-time boot menu"?? There seems to be so much confusion between us.
