In the logs - does it say anywhere how much VAT or sales tax a buyer paid on each transaction?
Just one thing that I noticed about the way you have set up VAT. As UK seller, I need to charge VAT to all EU customers at a flat rate of 17.5% and non-EU customers at 0%. It seems that your VAT option charges VAT at the local country rate which I suppose it set up for U.S.sellers. I have a way round this but thought you might like to know.
