Edit all

Edit all

Does anyone else have issues with the edit-all option? We can never get it to work. I'm not sure if it is something we are doing or it just does not work. 

I have 15 vertical blinds on a job, the customer wants a different fabric so I click on edit all and chose the vertical blinds, but when I go to choose fabric the list is empty, no fabrics to chose from 

Any ideas?
