Finally fixed the problem by using Gparted on Mint and formatting /dev/sdb1 which was the old OS that I moved to the SSD. Manjaro would sometimes point to the correct SSD OS and sometimes point to the old OS. Then ran sudo update-grub on Manjao.
But 1st I did a blkid on Mint & Manjaro
Notice UUID="522288d6-71d7-40f5-93e8-d821b0a9d915" which blkid reports correctly on Mint and incorrectly on Manjaro. Should be on /dev/sda1
Linux Mint
