Variable Product with Add Ons

I have a variable product where each color is a different price. Those products have add ons that will then increase the price depending what is picked. So I pick a color and it is $1,000 and then I pick an add on for $100. The price is $1,100.

If I go back and pick a color that is $900 it will now display $900 on the product page instead of $1,000 ($900 base + $100 add on).

BUT In the cart the price will be displayed $1,000. So the price in the cart is displaying correctly. The price on the product page is displayed incorrectly.

What is happening?? =[
