Switch between inc VAT and ex VAT

Hello on the site https://klitgaard-digital.dk/ i have issues with a popup that switches prices between Ex vat and Inc vat.

As of now, you have to click a couple of time for it to actually work.
If you go to the shop: https://klitgaard-digital.dk/shop/
You can see prices say: “Inkl. moms” as suffix.

If you press the Privat/Erhverv in the menu, you can switch to “Erhverv” this should change the prices to Ex vat, and set the suffix to: “ekskl. moms”

Right now you have to press this button multiple times before it works.

Code to help with functionality:
