No problem! All credit goes to an Era member who discovered this when they did this last time.
That's strange. I have one for 10% and one for 20% discount.
There is actually one more row below with "None available" that I presume has 30% code.
I was on mobile before but I checked on PC and have two codes as well :O. Thanks to you and the person who posted instructions before.
They were for 10 and 20 but the email was for 30 :S.
