[PS 1.7] New attributes are not visible

[MarSok18]

Hi,

 

I hope somebody can help please.

I created new attributes group (like size. color) "length" and I am adding a new attributes to that group eg. 1m, 5m, 10m.
Everything is ok, new group exists, attributes exists too, but when I trying add new combinations to some products, my group is not visible.
I have only three attributes group, those groups have been created at the begining when I installed Prestashop.
I renamed those group but on the combination list they still have original name eg. size, color.

How to add a new group and make it visible at the product combination list?
