user-profile fields in posts

[CeesT]

Hope to find a solution for my (VB-newbee) problem:

I have some "user profile" fields in use here; after importing from phpBB field-2 is the "location" field. I also like to use field-1 field-3 and field-4.

They are active and have the same settings as location/field-2 by changing them in the "user profile field manager".

When a user profile is checked, all the fields are there, but in the discussion-posts of this user, only the 'location' is visible together with the registration-date and number of posts.

I like to have the other user-profile-fields also visible in his posts.

I have checked the admin panel, but cannot find a way to enable these fields. Is this configurable in the admin panel somewhere I missed it?
Or do I need to change template for this ?
(or do I need to do a maintenance job after changing the user-profile-fields ? )

(using 3.6.8 patch2 here)
