Listings octupling and vanishing!! No Xmas sales!!!

Noticed rogue ebay system created duplicates in my listings last week novber 2023, manually ended them all...zero as sales now sixth week! Today, ended 200/579..went to Ended to Sell Similar and refresh them...the 200 unique items became 50 items repeated 3x, 8x, 7x etc!!! My vanished listings!!!!!!!!!

Yesterday it was an antique in my cart as buyer, quadrupled!!!

What on earth ebay?? Promoted, I'm never using again as it sticks old dates into metadata and ruins your ability to be searched "Newly Listed", what true collectors search by...you owe your affected sellers a credit, ebay this is scandalous.
