Text entry fields, line and paragraph spacing

Greetings,

I added a text entry field and selected "1.5 points" for line spacing.

On the slide view, the field behaves normally, with the line spacing. (You can manually fill those fields to test them) 

While previewing however, the line spacing switches BACK to 1.0 point.

Is there a reason why? I also noticed that paragraph spacing doesn't apply to text entry fields while previewing.

Thanks in advance.
