Sentence after a foot note not 'recognised' in 2017.

Hi, ever since updated to 2017 I have the problem that Studio occasionally doesn't 'see' the sentence after a footnote. With a text with, say, 25 footnotes, around 8 times after the clean-up the sentence after it is still in the original language. Does anyone else has this problem? I don't do anything unusual, I've got Windows 7 and Word 10, so it would surprise me if I'm the only one having this problem
