The required star is not behind the sentence but below

Sometimes the (red) required star is in the wrong place.

In the example you can see it at the family name.

This happens because sometimes HTML-code is automatically added to the text. By using the source code button 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.
