Change a lower price on products catalog and price

Strangely there are moments (I have not been able to decipher patterns in which they change, but it is accentuated with the activation of the plugin WP Super Caché) in which are shown lower prices, than the normal price in the catalog and sections of related products.
No doubt a challenge as it is very strange and dangerous for an e-commerce.
