I am trying to build a PB of John Donne's Divine Poems and Holy Sonnets and am attempting to add line numbering. In order to do this, I have tried to use tables in Word (3 columns, the second for marginal notes, and one row). Unfortunately, when built in PB, the line numbering is consistently slips.
This is a screen shot from Word,

This is a screen shot of the PB,

You will note that the line numbers go increasingly out of sync throughout the document. I am trying to work with verse over 500 lines long which, given this slippage, is unworkable.
I have uploaded the .docx which produced these results,
1667.Donne - Divine Poems and Holy Sonnets - draft.docx
I have cleared the formatting in the .docx and had originally set the entire document to 'no spacing'. The results of this, discussed here, are worse. I have, therefore, set the number column to 'Normal', which at least gives an approximation of the correct positioning.
There is some discussion regarding this here: http://community.logos.com/forums/t/37590.aspx
I wonder if this is a bug (hence posting separately), but I appreciate that what I am attempting might just not be possible (due to the limitations of either Word or the PPB tool), in which case, it would be good to know this.
Thank you in anticipation.
