Rounding currencies

Hello.

First question

Currently trying to switch from WPML til Polylang on this site

https://staging-z99skulpturerdk.kinsta.cloud/

When I reload the swedish products, the price switches back to the default currency DKK.
I have set the setting to keep the currency, here:

Should be correct right?

If you go here
https://staging-z99skulpturerdk.kinsta.cloud/skulptur/anerkendelse-motivation/manpower-2/

And then select swedish version
https://staging-z99skulpturerdk.kinsta.cloud/sv/skulptur/bronsskulpturer-sv/manpower-2-2/

And reloads, it changes to DKK again.

Second question

How can I change the swedish and norwegian pricing to clean them up, no decimal, and perhaps rounding numbers depending on the value?

Just repurchased the plugin for support

thanks
René
