Dual Manjaro entries on Grub menu

[CummingCowGirl]

I installed your Top-5Bootloader-Themes then proceeded to select Shodan and reboot. I noticed the layout wasn't all that great and that I had 2 entries for Manjaro, once rebooted I select Fallout and it looked much better during boot but still had 2 Manjaro entries on the Grub screen. Any way I can fix this?

I'd probably just install grub-customizer and remove any extra entries you don't like
