Random paragraphs aligned "in mirror"

[Marius]

Hi all,



I am trying to finish writing this paper but some random paragraphs align "in mirror". I have tried selecting more paragraphs (including the one that is mirror aligned) and then justify, left align, right align and still one paragraphs aligns the opposite way as to the others (see attached picture. The below paragraph behaves normally). Any ideas why this is happening? Freaking frustrating.
Thank you.
