Variations Doesn't Work After Updating Option Variants


I am using latest version of Cs-cart MVE.

I will explain the issue with an example;

I have option named Color and its variants Blue, Red, Yellow.

When I add product X with using this option and variations, everything works OK.

Then I update my Color option and add another variant, for example Green.

Right after adding these variant to my option. My X product's variations doesn't work anymore. But the product I add after updating the option works OK.

So, everytime i update an option, older products that are using these options doesn't work anymore.

Is there any fix or anything i am doing wrong?

Thank you!
