Default arrow - line mixed up in theme

[Reb T]

Hi,
I have created a new theme and wanted to ensure that all shapes (incl.
lines) that are inserted when someone uses it are a certain colour. So once I
created a line that colour, I set it as the default line. I used an arrow
line at the time to create the colour rule.
Now, when I use the template with the theme and insert a line (without an
arrow head) I get an arrow for all lines. How can I reset this so I can use a
normal line?
Thanks in advance.

Thanks Steve, but I can't find a way to reset it.
As it's an arrow already, there is no way to make it a line and to set that
one as the default - I can't even get a line...
Any ideas how to reset it?

Cheers
