We've been using a document template (called New Deed) for a few years set
up with styles Heading 1, Heading 2, Heading 3 etc linked to Outline
numbering via the styles box - so far so good.  Heading 1 is numbered, in
bold, all in caps, heading 2 (and all that follow) are numbered, not in
bold, not in caps.

One of my users has a document based on New Deed, which she attached under
tools and ticked to up-date styles.  Heading 2 changes to reflect heading 1
- ie bold and all caps (the numbering is correct.  

She says she copied and pasted some stuff in from another document and I
believe this may have had the formatting applied manually.

I've notice that in her document Heading 2 is now a paragraph and character
type of style and I cannot get it back to being just a paragraph.  

Is there anyway to clear this?  I've taken the Auto up-date styles so we
can get the document looking the way we want but I'd like to know if we can
clean it up?  Many thanks - great site by the way!
