Dual Booting 2 Manjaro instances

I have Manjaro KDE Unstable running, and thought to install Manjaro KDE-Dev on the same drive. I used Calamares to split my drive, and it seemed to install correctly. However Grub seems to only see the original Manjaro KDE Unstable. Any tips?

Partition table entries are not in disk order.

Chroot to the new installation and install grub at esp (same esp with old one).
Use the tutorial. Make the command proper, checking with lsblk.

Did you remember to do 'update-grub' at the booted up Manjaro OS (unstable)?

I am sure petsam's way would have also worked (I did steps 1-4, rebooted without success and I gave up when I thought I had to branch to the UEFI section).
