Tobias,
Have you set up KeyDescLinks between the lookup dataset and the subselected text-display column of the parent dataset?

i.e.
the Keylinks link the primary key of the lookup set with the nominated Keysource
viz.
LKP_KEY=PARENT.POLLING_KEY

the KeyDescLinks link the description in the lookup set with the subselected display column, let's say it was subselected "AS X_DESCRIPTION" viz.
LKP_DESCRIPTION=PARENT.X_DESCRIPTION

Otherwise,,,,
generally, you will see a blank if there is not a key value in the lookup dataset that matches the polling key in the parent. Related possibility - the keys not matching for case?

Keylinks relationships don't work if the lookup dataset uses the same query object as the detail dataset.

If there's no solution here, best you post the SQL for the parent and the lookup sets and shows us the KeyLinks and KeyDescLinks settings you have.
