When we are using VPE and we change the values of the Attributes/Properties the VPE information is gone.

At the first page load the VPE values are correct but once we change the attributes/properties is not displayed anymore.

Steps to reproduce:

1. Create a new Packing Unit (if you already don't have one) 1..1 Access Gambio Admin > "Packing Unit" and create a new one
2. Enable the Product Options module
   1. Gambio Admin > Modules > Module Center
   2. Search for Product Options (English language) and install it
3. Add one attribute on Gambio Admin > Catalog > Product Options with two option values
4. Create a new product:
   1. Set the VPE previously created to the new product and set its value to 10 (for example - VPE Value)
   2. Select Show Unit Price
   3. Set the product price to 20 EUR
   4. Add the attributes previously created with the following values:
      1. OPTION VALUE 1: VPE -> 100 (with the unit that you just created)
      2. OPTION VALUE 2: VPE -> 1000 (with the unit that you just created) / Price - Price Previx -> 20 +
5. Access the product page and try to change the attribute values
6. Try it with only properties, only attributes and both together

Expected: when the attributes are changed the VPE information should be displayed correctly
Actual: after changing the first attribute, the VPE information is not being displayed anymore.
