Product attribute backoffice

Hi all,

we created various classification attribute for personalize the attributes product.

When I go to backoffice and I select the attributes there is a list of attributes that I can modify.

When I populating the attributes, the save button is not enabled and I can't save the modification. For that reason, I modify the name of product, so the button save will be enabled: after that i click save and the name is updated , but attribute value isn't changed.

Do you have any idea about why this happen?
