Cross sell and variable product price error

I’m testing cross-sells with frequently bought togheter.
I have this beavhiour
when I create a cross sell with a variable product with two different prices, when created is set the variable product as THE PARENT , but the price of the bundle gets locked at the lowest value when added to cart.
so:
variable product 1 (90) + producB (5) gets = 95
variable product 2 (110) + producB (5) gets = 95 ad the lowest
in the preview on product page is right, than in the cart reverts back to the lowest value, as the bundle product is saved.

am I mssing something? is there a way to create two bundles for each variable price change?
