Style colour not saving

[kungfauxn00b]

Hi, I've had a quick search and can't really find any answers.



I've created a template (MS Word 2010) with various styles for questions and answers with the idea that I write the answer sheet, save the document, then white-out the Answer style and save that as a copy.

On brand new documents, this works a treat. However, when I copy text from an old version of this document into the template (pasting as plain text and work through the formatting page by page) when I change the Answer style to white. save it then re-open it, it reverts back to the original style.

I know it must be something to do with something being brought across from the old, original document- I just have no idea what!?

If it makes a difference, the old documents were most likely created in MS Word 2003 or below.

Thanks in advance.
