I imported your atttached listings and also checked your CH3 and CH4 listing online at eBay.
As far as I can tell these are all different listing, they all have a different eBay item ID!
CH3 on eBay, item ID: 282504906300
CH3 listing in GarageSale (ended), item ID: 272296633604
CH4 on eBay, item ID: 272697559402
CH4 listing in GarageSale (ended), item ID: 282089896093
So, the listings in your GarageSale are different “versions” of the listings on eBay. You maybe relisted/started them outside GarageSale or you relisted/started them from within GarageSale but then deleted them by accident and keep the other, ended ones.
