MarketPress variation prices are not updating

We are setting up some products with variations 2 variations per product. When you are on the product page and you change the variation of a product the product price does not change to the proper price. We have tried this on two servers. I test server and Our actual server with the same result. We have also tried this on the parrot theme and the 2016 theme with the same result.

The prices are correct in the mini cart and in the checkout page, but not on the product page. Though the last variationof every level does update. So for example we have to variations per level but with four option per pair of varitions. The first 3 will show the same price though they are different and the last will show the correct price.
