eBay shipping help

[Twin Mom]

I haven’t sold on eBay in a long time but I’m not getting enough traffic on Mercari for some items so I figured I would give eBay a try. I am trying to list something and when I choose the option for the system to calculate shipping based on the buyers zip code it looks ok but then when I preview the listing it shows to ask the buyer for a shipping quote. Does anyone know how to fix this? I did not allow international shipping or local pick up as options. Hoping some of the eBay experts on here have run across this and know how to fix it!

Thanks for your help.
