Sometimes the (red) required star is in the wrong place.
This happens because sometimes HTML-code is automatically added to the text. By using the tags-softkey in the screen where you can adapt the text of the field, you will see the text in HTML-code.
In front of the text you will see the code <P> or <DIV>. Behind the text you will see the code </P> or </DIV>. If you delete these 2 codes, the (red) star will appear just behind the text.
If you want to use some extra space, you can put a return ("Enter") in the 'Low' or 'Upp' of the field.
