How do I get rid of what I believe is paragraph spacing in outlook?

I use calendar items all day long. If I dont remember to hit Shift and Enter, it gives me a Double Return (Double Line Spacing). I want something that looks like this:

Name:
Occupation:
Phone:

I only get it like this if I remember to hit shift and enter.

Otherwise, If I just hit enter, I get this:

Name:

Occupation:

Phone:


I just want a regular return. I dont want to have to hold the shift down.

Any help in turning off this feature would be appreciated.
