Display issue with sale price

Hi

Im having issues with using the Price and sale price feature.

When I use the sale price feature the sale price text is over the top of the product title text (or under it) this is the same on the Single product page on the Related Product section under the main product here…

As well as on the main shop page here on the middle 2 and maybe if I chose that option the first products here

Please advise

Thanks
