In the cart on our store, it's calculating the totals wrong. If you add a product that has no options, it adds the total correct. If you ADD the same product to the cart that has an upcharge on a product, then it changes the total for the first product to have the upcharge as well. IE: Add a $49 product to cart. Then, add the same product but with a $10 upcharge, then the cart changes the $49 to a $59 product. Now, both products are $59.
Example:
https://formalfashionsinc.com/dresses/express-dresses/style-c3765np-e-value-knit-dress-ready-to-ship...
If you select, size 0 (or any other size that doesn't have an upcharge) and add to cart ($49). Then, add the same product, but size 18 (+$10). The second product is $59 now. Now, go to the cart. It now made the first product you added $59 as well.
The problem doesn't happen if you add the product individually, it's only if there's more than one product in the cart.
I contacted the theme developer and they claim it's not them, for they tested with the default theme and it's still happening. I had this running on a development server before I copied it over and made it live. I went back to the development server and it's not happening there. The only thing that's different is that on the new site, we're running the latest version of the theme (Claue) and Magento 2 (went from 2.3.5 to 2.3.5-P2). That's why I thought it was the theme.
Frustrating. Any thoughts of how I can fix?
Magento 2.35-P2
PHP 7.3
Extensions:
MageWorx Product Options (latest version: 2.31.5)
