So the issue that I have is concerning about the product variations.
I'm using two different attributes for this shop - color & size.
I create all the variations automatically, based on values of these two attributes and they're all created, associated with the unique SKU numbers.
So the issue can be seen on the following url:
If you choose the "Black Grey" color option and try choosing different size values from the Size dropdown you'll notice that it will not let you to choose all of them.
I would appreciate any advise or a solution for this issue.
Thanks in advance!
