Problems with the default combination which is not present

[neeky]

Dear all, good day!

I found a problem in the Prestashop 1.6

 

In my online store all goods with combinations (all products have sizes, width and height).

In the settings I disabled the ability to do order when products have 0 stocks and disable showing attributes with 0 stocks. I think this is very useful when 0 stoks combinations are not display.

And now the problem.

If the default combination became 0 stocks, product bocome not available to order in the catalog, and when you go to the product itself,  default combination is not hidden. 

It is OK with non-default combinations, they are hiding.

How I can solve this problem?

Sorry for my English, I hope you got the problem.

Thank you all in advance!
