Crossed out Price not showing without scheduling dates

Hi
I’ve been updating products and I ve found out that only the discounted prices are being shown in front-end of the single product pages I’ve updated, even when normal prices are written in the back-end.
However the crossed out (normal price) does appear when I add an schedule for the sale.
The issue is recent, because this was okey a week ago, is there any way to solve this?
I would like to both , crossed out price and discounted price, to appear at the same time even when there isnt any schedule for the discount, because these product are always on discount

Thanks you in advance

Greetings
Aaron
