Looks like I missed a sed command or two. I usually write out "underscore" in the script so I read it literally during recording: https://i.imgur.com/j3RdHA5.png
I write out punctuation like underscore so that I know that is what I am literally saying to the camera. I usually edit that out. Apparently I missed out on that this time. Oops! Sorry. I'll put that on the checklist for next time (half considering making tests fail if I forget to do it).
