Wh can't I map Robohelp styles involving bullets to styles in my Word template?

I have a style called Bullet in Robohelp, which is defined as a bulleted list style, and looks

• like this

in robohelp.

I have a style called Bullet in the Word template I want to use to generate output, which is also defined as a bulleted list style.

When I get to the Print Document Appearance screen adn select the Word template, I see 'Unassigned - use style in project' against the Robohelp Bullet style entry. When I open up the list of styles available in the Word template the Bullet style is not included in the list.

This is costing me much time - every time I generate a document that uses the Bullet style I have to go into the Word document and apply the Bullet style to each relevant paragraph (and remove the spaces between the bullet and the text, but that's a problem for a different day).

What do I need to do to get the mapping working properly?

Thanks in advance!
