Marked Down Sale Items

I have a product listing with multiple variants/colors included in the same listing. Some of these colors are on sale with discounted prices, but the issue is that all variants are showing as “on sale,” even for colors that are not discounted. For example, in the Echo Pearly Shirt listing, the non-sale variants display a slashed price followed by the same price, incorrectly marked as on sale. I’ve provided a link below for reference. How can I adjust this so that only the discounted variants are marked as on sale?

@JoeyRoo i you have multiple variants, one of them might have less price, therefore the product can be marked as on sale
