Why are discounted prices not showing on my website after theme changes?

Hello everyone, someone could help me with this please? I have a 50% price comparison on my Shopify products. This worked perfectly until a few minutes ago when I added a featured product and made some changes to the theme (nothing that involves these comparisons) And when you enter my website you can no longer see the crossed out prices, you only see the prices as if They were not on discount. But, when entering the editing part of the topic, the crossed out prices do appear, but not on the real page, which is very strange, any ideas?
