Tax On Order Total not individual items

I am trying to add TAX to my products using the condition

1) if entity has field order:product:0:node (name_of_field)
and
2) Data Comparison
order:product:0:node:name_of_the_field equals yes

My Question is
1) Only the first item gets checked for VAT not the rest is there a way to loop through order parameter and
2) Even if the first item gets checked the whole order total is getting taxed rather than just the product price.

but the Tax is being applied to the whole order rather than the Product Price.

I had this working previously but there was an update done to Ubercart and now I am not sure whcih version it was .
