Problem with Backing up Group Text Message Strings Using SMS Backup+

[Android Central Question]

Trying to back up SMS messages from LG G5 cell phone to the computer in order to print out group discussions that require saving in hard copy format. I am finding that almost none of the group text strings include all comments as found on the phone. What I generally see is that only one member of the group shows up and beyond that, it usually excludes my own texts as well. Is there an easy fix so that I can get the full comments from all participants in one file for printing? Thanks!!
