Specific price - Bug when modifying order

[jemm971]

Hello,

I saw a bug when using specific product prices for a Group of client :

I defined a client Group named "Pro", and added some professional clients in this group. And then I defined specific product prices for this group.

And it works from the front store, my profesionnal clients get the professional prices.

BUT if I want to modify their order in the back office, there are some bugs :

- if I add a product, I get the good professionnal price (in total), but the price on the line is the normal price instead of the specific price (so total of the lines dos not equal the invoice's total)

- if I modify the quantity of a product, the price applied is the normal price (except for the first quantity?), and I have a false invoice's total... (which is not the sum of normal price, nor the sum of specific price...)

Is this a known bug? Because with such an issue it is impossible to really use specific prices... and I need it because I sell BtoB with these specific prices (and BtoC with normal prices).

And it was one of the reason for me to choose Prestashop. Anyone has a solution ?

Thanks.
