Gallery Auctions of 1155 fixed?

I just created an Auction for a 1155 token, but it shows different things as the other 721 i’ve made before.

It says “Price” Insead of “Reserve price” and says “Buy 0.18 per Token” instead of “Place Bids”.

This means is not possible to start an auction with 1155 tokens in the Gallery App, but they are sold as single editions with fixed price (althrough is a 1/1)?? would love to know so I don’t waste gas.

It should be possible. Are you certain you didn’t choose fixed price when you created the listing?
