Problem with the output when no Menpunkte available

Wow, cool features this forum has! Praise to the admins first time ..! So I'm looking for help to the following problem: I have about the Extension Kickstarter created a new extension that extends the FE-User Tables 2 to other fields, so that they can be gefttert and backend data. It is merely 2 string fields. The works so far. The issue on the website I would like to do with the newloginbox user list, which also works as far as, to the title of the column in the table. In the list where the top of the <th>, for example, phone, email, street stands, etc. for my new field appears only something like this: [tx_feuserhelcotec_user_unit] and including the values of the input fields. This has surely something to do with local or long translation, right? Where can I find these values? Hopefully I've written it understandable divertikulitis :)
