My /etc/default/grub is:

$ more /etc/default/grub
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="resume=/dev/mapper/fedora_lea00-swap
rd.lvm.lv=fedora_lea00/
root rd.lvm.lv=fedora_lea00/swap rhgb quiet"
GRUB_DISABLE_RECOVERY="true"
GRUB_ENABLE_BLSCFG=true

So here is GRUB_DEFAULT=saved.

Latest kernel is 5.2.17-200.fc30.x86_64

My /boot/grub2/grubenv is:

$ sudo more /boot/grub2/grubenv
# GRUB Environment Block
saved_entry=f7addef1929b4033b5d242667945cf04-5.2.17-200.fc30.x86_64
boot_success=1
boot_indeterminate=0
kernelopts=root=/dev/mapper/fedora_lea00-root ro
resume=/dev/mapper/fedora_lea00
-swap rd.lvm.lv=fedora_lea00/root rd.lvm.lv=fedora_lea00/swap rhgb quiet
