When using footnotes I notice that sometimes there is a gap at the bottom of the page and the paragraph continues on the top of the next page. To fix this I copy/pasted reference links after the citations. The http: link was long enough to drop the text one line. Dropping enough lines seemed to fix the problem for one page, but then 2 pages down there was another gap.

I tried typing within the gap but it would just drop down to the top of the next page. I'm not sure if you understand what I'm trying to explain but if you do, is there a way to make sure the gap disappears so the paragraph goes completely to the bottom of the page?

I am using Office 2016.
