Hi DrByte,

I'm seeing this problem on my store too. It seems to kick in when the delivery address is in another tax zone. In my case zero rating a sale for export to the US. You then end up with this on the payment page "UK VAT (20%) + VAT Zero Rated for Export:". Vat is charged on the items and any store collection charge is zero rated.

I've tried on PHP 7.1 to 7.4 and it is the same. Previously I was on ZC 1.5.6 and the issue appeared when I upgraded to 1.5.7b.
