I need help with trials of gmones I have my secret code unlocked.And I keep typi

So

 I was trying to do trials of gnome And I did all.

Of the trials in the order.I got them and got all the secret parts for them.And I was trying to do the rainbow guardian.And I typed my secret code in correctly multiple times and it still won't let me do it

I did all 4 of the trials first I did the blue one. Then I did the red one, then I did the green 1. Then I did the Yellow One. Did all of the passwords? They all worked fine. I destroyed the guardians and I even have the secret password. But the secret password will not work. I cannot activate the rainbow guardian. It will not let me. So I can't open the 2 rainbow star chests
