I have the Abundance theme on my web store. The product categories and subcategories on my store are positioned on my left sidebar. I drag and drop these categories and subcategories into a specific order. But, a strange problem happens in that when I drag and drop my product categories into the correct order they will stay in that same order for a little while but within a few days some of the categories will randomly change order. They just won't stick in the order I've set by dragging and dropping in the product categories page. There is no rhyme or reason as to what causes them to move, although it often seems like the same ones move out of order at various times, but not always.
Here is where you can see the categories both on my left sidebar and on the product icon order:
I am using the WooCommerce Product Categories widget within Abundance and it is set to "Order By: Category Order"
Any idea why this is happening and how to fix?
