Space marker.

Michael Munn

hi all, today in school i experienced this problem with my school use computer. 
I opened the new document that were sent by my Science and Geography teacher at different times. When I opened both documents I get this message. Every time I press down arrow Jaws told me there is a space marker. and my Braille display  showed the Symbol of dot 4 and Dot1-6 sign. Can someone please figure out what is this and how to trouble shoot? All comments are greatly appreciate it. 
best regards 
michael Munn
