Trial of Gnomus code not working although I’m putting it in correctly

I know what your thinking “another person who doesn’t know how to put in a code right” but this is different. I’ve already completed the red, yellow, and blue trials, entered the code, defeated the bosses and gotten three parts of the final code. The problem is whenever I enter the green code so I can fight the green guardian boss it doesn’t work. I took a picture, wrote it down, went back to the trial and took another picture, got two people to read it off and confirm I’m putting it in right, asked for help on Reddit, but for some reason it never works. Please help me!
