Whenever I edit a customer's response (I do this every now and then to remove email signatures and extra linebreaks, so our requests require less scrolling to get through for our agents) the comment is automatically set as Internal, regardless of whether I'm using the Comment Internally or Share with customer button. This started becoming a problem after moving our server installation to docker, and in a new production environment. We also upgraded from 4.5.x to 4.8.1 shortly after performing the move, and none of us thought this to become a problem, so I can't say for sure if this happened as a result of the upgrade, the move or both.
Have anyone stumbled upon similar issues, or have any ideas of where to look? I can't seem to find any place where the reason for this behaviour would be explained.
