Hidden columns in userlist

Hi everybody,
I'm facing a quite annoying problem: I created an userlist with the basic data of the users, but some of the columns look to be hidden, in some way.
I mean, the columns are firstname, lastname and mobile number: the latter is empty, even if on the user data the field is populated.
Did anyone get the same issue? Any hint on where to look for showing/hiding column content?

Thanks in advance!

Probably just access issues to those fields. Suggest downloading and reviewing the CB Primer Book carefully. Especially the field configuration sections.

Hello Kyle, problem solved.
Actually, it was an authorization issue, neither for fields nor for the list, but for the tabs instead.
