Currency’s are not converting to the correct price

Hi I have just noticed that currency on my website no-longer converts to the right price.

For example; Minerva Owl is £6750 and $6935. https://www.shaktiellenwood.com/product/the-minerva-owl-amulet/

Can you please tell what’s going on here and help fix the issue.
