Custom Field MultiVariant bug

[johnkont]

Joomla 3.7.5
PHP 7.0.22
VM 3.2.4
Template: Protostar

Product with multiple variants.

The 1st variant is the product itself. When you choose another variant, the 1st variant dissapears.
You can choose the 2ns 3rd or any other variant without other problems. Only the 1st dissapears!!!

I have the same problem from day one.
I had noticed today that if you have more than one ramifications the choice who disapears is from the last ramification only.

Please advice or update, is a problem!!!
