Disconunt, custom fields in product not work as expected - making biger discount

[kacper1972]

Hello

I have big problem.
I have a product with some options. Option a cost 6 EUR, option B 10 EUR, majn product cost 100 EUR.

The problem is this. if I apply the discount to the main product and the customer to select an option then the discount increases by this option. But selling price does not increase.

The customer buys the product in my store is going to get two rebates, first - discount, and the secend from the options. Why from options??? Options should increse price

Please look at the attached picture

I use to make product options - a string
You can see it na picture discount back

More strange is that the prices in cart is not good - picture discount cart

Please help
