https://subeta.net/user_shops.php/shop/52491/find/rain These three items are showing as Display only, even though they were autopriced. I tried manually adjusting the prices and even waited a while and came back.

if its the 2 unstaple fairy plushies and zoe daydream item, autoprice wont do those as they are more than the max limit it does

regular autoprice will only price up to 5,000,000

to go over that youd need to pay some sp to use the 'super autopricer' which prices up to 100,000,000

as for manual, not sure what happened if after entering the price and hitting update changes

It shows as display only, but it can be purchased via shop search.

It wasn't those. It was a few cheap items that were only like 50k.

Odd. And now they are gone, and don't show in my sales history.

The Rainbow Vesnali Egg is there, but that's the only one I saw when I went to your link earlier. If the items sold and aren't in your sales history, you should certainly file a ticket. I hope it gets sorted!
