Reply To: Text flow issue – lots of white space at the bottom of the page

I figured out what is happening, but I have no idea why!
On my screen shot the pages are right to left. (I know the Hebrew is incomprehensible to most of you, but the numbers aren’t)
Footnote 14 and 15 on the left hand page are in one sentence. Seems that they insist on remaining together. When I moved 15 to the next paragraph, all was fixed.

Now if anyone can explain why this happens and how I can fix it (I can’t leave the footnote on the next paragraph!) I’d appreciate it!
