After i change item ordering "Inherit from category" to "Most recent first" and save, it doesn't change. I mean, it's still "Inherit from category"

What was the category's ordering?

Order was inherit from category, but it looks like ordering by item ID.

Hi. As it is written right above it, the ordering you are trying to change is applied only when you select a single category. Since you have selected more than one category the ordering value can be found under the section "Layout options for multiple category selection".

Thank you very much. I was tryin' to do it right 3 days.

You are welcome. Obviously we need to improve the interface so confusions like that are avoided.
