Moving Product Category Order (WooCommerce) is not working

My client has an Avada theme site and she wants to re-order the product categories in WooCommerce. I tried to move them in the admin area, using the right-side drag and drop mover, but nothing is moving. It looks like it will drag and drop, moving the other categories to drop in, but the page refreshes and nothing has moved. I’ve asked on the Avada Facebook group, and I’m asking here.

Anyone seen this kind of behavior and have an idea why it’s not working right? I’ve done some searches here and I’m finding more about product movement than category movement.
