Price in default currency not displaying correctly

Hi,

Some time ago the prices for some of our variable products started to display incorrectly in the default currency (€). The strange thing is that not all of them are displayed incorrectly, even if they have the same settings/prices.

Also, some customers in Sweden, that should be seeing SEK for these products, are complaining that, for the same articles, they see the prices in €

Note that these are variable products in Woocommerce but we are using “Icon show single variations” plugin to display the variations on the archive pages.
