You need to edit the template (open the letter, right click and edit)  and in the template, you will need to adjust the ##endifs and spaces, LIke by example, if you see:

#endif

#endif

#endif

which consumes 3 blank links, you can change this to 

#endif#endif#endif

Its not an easy task and there are differents provinces etc. so its complex. Usually, to make changes, I add some prints in the form , by example , I would add lines in the template  like this, and it telles me where I am in the template
