Hi. Did you maybe insert them using the checkbox on some and unchecked on others in the listing details window?
Other sellers' items may not be showing because they haven't had time to index if you recently listed them. Mine take 6-8 hours consistently.
I tried finding your listings and there were none with the user ID you have here. Would you post a link please? You're allowed to put a link to your other items in your signature if you want.
