WOOCS and PPOM

Hi, I’m using WOOCS with PPOM Pro. I was led to believe I needed PPOM Pro to be WOOCS compatible. However, when I set ‘allow multiple’ to ‘yes’, the cart is double converted.

When I set it to ‘no’, the prices are correct in € in the cart but the checkout process is in the default currency, which is CZK. That’s not what I’m after, I want the customers to be able to pay in € and see all the prices in € in the checkout. Is this not possible?

I’m not sure what plugin is doing this, so I’m not sure which support to contact. I’d be glad for any help!
