label undefined

Hello, I am using version 1.4 since 1.7 when I update the name that shows in the colors shows as “undefined” does not show the name of the attribute, does this have a solution?

Currently when you put on top of the woven attribute it shows you the name, but when I update the module that name no longer shows it, is there a solution?
