presentation does not take on custom bullets, why?

[Tangy]

When I create a custom PowerPoint template and use a custom bullet in the
master slides when I then import a presentation onto that new template it
does not take on those custom bullets and I have to go through and put them
in manually. Why is this? What am I doing wrong?

Thanks

If you reapply the slide layout to the imported slides, do the bullets
"take" then?
