Hi Kate,

I'd say: either don't apply numbering to the lines that
should be bulleted OR set up an outlined numbering list
"style" and apply that, so that Increase Indent
automatically applies the bullets (next outline level).

But it would likely be best to start over in a new
document, at this point, since your current document has
become unstable. Select your numbered lists, go to
Format/Bullets and Numbering and set the numbering to
"None". Select all the text EXCEPT the last paragraph mark
and copy/paste to a new document.

Now go back into Format/Bullets and numbering/Outline and
create a numbering preview (use the Customize button) that
looks the way you want it (number at level 1, bullet at
level 2, using the indent settings you prefer). Apply this
to the numbered lists; in order to create the bulleted
items, select those paragraphs after numbering them and
press Shift+Alt+Right Arrow.
