Possibly the issue is that you have copied and pasted from Word. If you view the source code the HTML produced by Word is awful and full of 100's of lines like those below
<!--[if gte mso 9]><xml>
<w:WordDocument> <w:View>Normal</w:View> <w:Zoom>0</w:Zoom> <w:TrackMoves/> <w:TrackFormatting/> <w:HyphenationZone>21</w:HyphenationZone> <w:PunctuationKerning/>

It is best not to copy and paste from Word as it produces all sorts of none compliant HTML code that messes up formatting in many browsers.
There is a 'Paste From Word' Tool in the NewsPad WYSIWYG RTE Editor, this does it's best to remove such code, but as there is so much it's not perfect and it's best not to copy and paste from Word at all.
