Why isn't my currency selector working correctly on my new theme?

Hi,

I have an issue with the currency selector with my new theme, “blockshop”. When I try to change currency on the page it redirects me to the live and published store (different theme) and I should mention I have installed Geolocation already and the needed currencies have been set there.

I didn’t make any changes on the selector and it was like that from the beginning.
Can you advise me on how to fix it?
