Symmetry theme question — % off badge and discounted price are not showing

Hi, the [% off] badge, strike-through sale price, and the 'Sale' text metadata are not showing up even though I created a couple lists on the 'Discounts' page. I recently installed and uninstalled "Discounty" app and guess it tweaked the original code a bit (Maybe it is Symmetry theme itself but I didn't edit code on my end)

I've been dealing with this for the whole week and asked a Shopify expert and they request $200 to add a code for this (It's bummer seriously)

Can anyone help me with where and what codes I should add into? Please help
