I need some help with VM Invoice.

In my virtuemart i dont want to show any decimals in the product price, so i have turned decimals off.

But in the invoice its very important that the vat is displayed without any rounding and with decimals. But i cant get this to work.

I have virtuemart 2.0.14 and VM Invoice 2.0.20. I have set "Tax Summary use rounded values" to "No" but it has no effect at all.

Its required by swedish government to declare the full VAT so it cant be rounded in the invoice.
