Removing Red Comment Arrows in Convertered V15 File?

Hi Folks,

I'm converting V15 files to run in Prime 8, but can't figure out out to remove the red arrows and red lines.  The file runs.  Right clicking on the arrows doesn't do anything.  I can't find anything in the online documentation.  I must be missing something.  Can anyone enlighten me?

Thanks,

Mark
