Aizome Bedding™ review for PreOrder Now Backorder WOD

I have contacted you without getting help. I haver used the from and nobody got back to me. The issues was that when you alternate between color some available some preorder eventually the button would only show pre-order even for in stock products. Now I deleted the app, and some of the code remained. How can I fully remove all the code? Batch and preorder button still show up.
