After updating to VM 3.4.3.10020 all payment methods are shown when selecting a payment method in the checkout, even when they shouldn't be shown depending to maximum and minimum amount of an article.
After downgrading to 10014 everything works fine again.
something to do with this?

Yes. Now that I have understood this, it works fine.
