Wanting to remove color for burgundy

Hey guys! 5 months ago, I dyed my level 1 wavy, virgin black hair with L'Oreal Feria Permanent Hair Color in the shade Chocolate Cherry 36 and nothing showed up. It was in very specific lighting that it did. Now I want to try again for a deep burgundy and was wondering if you guys would recommend a color remover or bleach bath. I have the ion color remover packet at home right now that a Sallys person gave me. Honestly, I am very scared that when I dye my hair again (I plan on using Ion Color Brilliance in the shades 4IR and 5VR) its not going to show. I will say that I did a strand test with those two colors + 30 developer and nothing showed up, now I am thinking I must remove the dye that's already in my hair.

Please give your recs and what developer to use with the color after the method of color removal! Greatly appreciated!
