Manual product selections in my Collection do not save

Hello,

I’ve searched online for answers to this particular problem but couldn’t find any that were specific to this.
Basically, in my Shopify Collection, I am typically able to sort my products using the list options provided (Bestselling, A to Z, Newest, Oldest, Manually, etc.) without issue.

These Steps typically work for me:

  1. I update my “Manual” list, putting certain products in a specific order
  2. Then I switch to another list, for example, “Newest”, to further edit any new products
  3. Finally I switch back over to my “Manual” list (where everything is usually right where I left it), so that my products will reflect this specific order on our website

*Usually that’s all I need to do. But lately when I finish Steps 1 & 2, and continue to Step 3, my previous “Manual” selections from Step 1 are gone. And instead, the “Manual” list reflects the order of the last list I was in (for example, “Newest”).

Is there a way to ensure that my “Manual” selections stay in place, regardless of whether I view other lists? (Newest, Oldest, Bestselling…)

It doesn’t seem to be a “Save” issue, as I get the pop-up at the bottom of the screen that says “Collection Order Updated”. But it doesn’t save my Manual order if I switch to another list. It just resets.

Any solutions to this?
