We find that many listings make inconsistent child variations,one pack and two pack appearing in the size variations at the same time, they shoud put different size but they add two pack and different size, as the follow pic shows, we also contact the seller support, they said the listing exists inconsistent child variations and told us we can report abuse, but we contact Amazon many times, but the e-mails showed they can't take action automatically, we don't know how to solve this serious problem.
