Selling G9 covering mislead me into thinking g10 exists. Cannot undo junk feed.

I messed up my 19/20 star G9 chocobo because I thought there is a G10. It was only till after feeding grade 1 feed to it, I started to realize their might not be a G10 because at G9 my stats were out of 500. GM could not do anything to help me but hugest I write on the forum for suggestion.
My suggestion: STOP CONFUSING THE HELL OUT OF PLAYERS BY SELLING G9 COVERINGS WHEN G10 CHOCOBOS DON'T EXIST!!!!!
For people that don't know, the new chocobo is one level higher than the coverings.
Suggestion two: Let people reset their feeds.
I now have to get my chocobo to 40, retire it and breed it x amount of times and spend more MGP. thanks.....
