Hello,
You probably hit the money limit since its been so few products. Call eBay and ask for more limits. Do not mention dropshipping if you can. Tell them you will sell products of about $50 average, maybe used, from your house. (avoid mentioning/listing electronics, gambling, knives, liquids, weapon related, virtual, COVID, VERO etc)
eBay usually increases limits every 1 month, sometimes automatically. However , there are some people offering faster list limits increase. I dont know how they do it, but I never needed it
