CRM Merge Template Footers misbehaving

CRM Merge Template Footers misbehaving

I have a set of Mail Merge Templates with Headers and Footers, the Footers will not hold their format after being saved. 

The issue is 'extra' blank lines appearing which pushes the Footer up the page leaving space below the footer image which looks ugly. 

I can edit the lines out, click save come out of the template and go back in and the lines are back.  I have also tried changing the wrapping on the image from Inline to InFront again it seems to work, I save it and come back and the image is back InLine.

All other changes including those made in the header seem to save without problems and remain when I come out and go back into the template.  This is happening on more than one template.

Thanks
