Mainsail is just the gui which starts this progress. Moonraker is doing the metadata extract part. So this Bug is a Moonraker bug.

Just my thoughts to this issue. Cura use a UFP file, which is like a zip file with a gcode file + jpeg/png thumbnail. if you upload it, Moonraker will extract it and store gcode + thumbnail. When you start a re-scan, it drops all metadata + thumbnail and then cannot extract a new thumbnail from the gcode file (just because the gcode file never had one).

Pls create an issue in the Moonraker repo. For your personal usage, you can also include thumbnails in the gcode file and dont use the UFP files. Here you can find all important settings for Cura to use it "the best way": https://docs.mainsail.xyz/slicers/cura/
