I've developed different types of packages. It was working good, and today I added a new one. I Did like all the other ones, and suddenly, when I list products, it shows the title of the costum field ("embalajes").

I don't know if it's since I added the last type (hasn't change anything on the configuration) or since the last hikashop update (updated it yesterday). How can I take off the title off the listings?

Here 's a picture so you understand better what I'm trying to explain. Circled is what I 'd like to take off:

That was it. Thank you again, Nicolas.
