Default description text disappearing

I am currently creating a template that uses the default property of the description tag to layout and style default text for a mailing list newsletter - so anyone at the clients company can just jump into a new email and change the correct details.

This works fine, but whilst testing I notice that when I try to edit a field that has default text applied that it will disappear, which kinda negates the reason for using it in the first place.

Any help would be much appreciated.

<$description default='Tuesday to Saturday Evenings at 7.30pm. Sunday Matinees at 3.00pm. Saturday matinees at 3.00pm (from x Month).'$>
