Table not showing the correct column from foreign key

When I define a foreign key in a table within my dictionary, scriptcase shows the wrong column als the field to show. I tried to change that, but there is no save button on this screen. Going back and updating de table does not save my change. When I create a new application the wrong (by scriptcase selected column) is shown. I do not understand what I have done wrong. Suggestions are very welcome.

Without this working correctly the dictionary is useless for me.

Thanks in advance,
