fullscreen + woocommerce

Hello, I put a product on sale but in the page it does not show the new price (it just shows the old one crossed over). The ulr is http://162.243.63.85/product/magnum-centenium/ . Is it because I put some theme font in white? (I tried changing the ones in white to color but couldn't figure it out) . Besides in the product page, I tried to put the content alignment in "center" but after saving the changes it turns to alignment "default" again. Kind regards, Valeria
