Strange behaviour on repeater in CMS

[nabo]

Hello

I have a repeater that contains two field: a page reference and a textarea.
The page reference is a list of user. With superuser all works correctly but with other roles (that have the correct rights to see and edit user as long as pagereference and repeater) there's a small but very annoying problem. I attach some screenshot

 

This is what superadmin see. After the #1: and #2: there's the email of the user page reference. The email field is the field that I choose to set as label field.

This is what another role see

but... the strange thing is that if I open the row, the pagereference is working correctly

so... what's the problem with non superadmin user? Thanks
