We have had several instances of Xpression MOS files in the ENPS scripts not show up in the Studio playout rundown. When clicking on the MOS file inside of the script, the video player window comes up and it's reading it as a MOS video file instead of an Xpression MOS file.We've also noticed that the color of the MOS file as a light teal, which matches the color of the MOS video file, but when the Xpression file is correct, it is a dark blue color. This is a random occurrence that does not happen in any regular fashion.
