Using DNN 5.6.2  and SC 4.36. I setup a required variant that has three choices.  Each choice is to display a condition variant that are set as not required  with various options and prices.  So far I have seen two issues:

On the products detail page the on the initial display the price is incorrect, it has already added in one or two of the conditional options price.  And not the one displaying.  If I choose one of the conditional variants it adds the price change OK, but if I change my mind and switch back to the basic product choice the conditional variant price is still added in. So even hough the option is no longer displaying it remembers the price change.  The price being displayed must always match the variants being displayed and not remembering previous options.

The Buy Now button is messed up.  It shows a small "button" with no text and it doe not do anything if you click on it.
