Why are sale percentages displaying incorrectly on my product items?

[QueenofHearts]

Sale items are not coming up with the correct sale percentages - the percentages are displaying way higher. Here is our sale collection that pulls the sale items: https://queenofheartshemp.com/collections/sale

I have products with variations where only one variation is on sale. On the Sale collection page, the items show the percentage like this: 

When you click into the product item though, and click through the variations to the gallon variation that is on sale, there is no sale percentage off in red displayed and you can clearly see that the sale is not a discount of 83%! How and why is this happening? It is happening on 2 items in my Sale collection.
