Apologies but I don’t seem to have the same options in my dashboard as in the link you include. My dashboard only offers control of what appears in the “sorting dropdown”, but not the order that the listings actually appear in.
Here is what the sorting options dashboard says, please advise again thank you:
“Click on any box below to make it appear in sorting option dropdown on Culinary listing and search results. To make a field available here, go to custom fields tab and expand any field from selected fields panel and tick the checkbox saying ‘Include this field in sort option’.”
