Hi Debra

I think the first order problem here is most likely that your Normal style
is set to Automatically Update. See

http://www.mvps.org/word/FAQs/Formatting/WholeDocumentReformatted.htm

Possibly you have also got the 'Automatically update document styles' ticked
in Tools > Templates and Add-ins.

The second order problem is that bullets and numbering applied from the
toggle buttons are unreliable at the best of times - a better solution is to
use styles. See
