some data won´t display in back end

[gulmue]

Hi!!
first, I think this component is very good, but I just have one problem with viewing the data.

In the Display data option of the back end menu I see only a few of the field with data, name, phone, but I don´t see the email.

I check the mysql database and the information was there, but I can see it in the back end

Any Idea how to fix this?
