Page view is distorted on currency change

Hello,

We discovered that Woocommerce products that use “WPC Product Bundles for Woocommerce” have one problem.
With PLN (Polish zloty) they work fine:

but are distorted when EUR is activated:

I believe that WPC plugin works fine, as with PLN it’s OK. Do you have any clues what can be wrong? I can send you credentials if you need them. Thanks
