Rescan adds camera model outside manufacturer (1571)
I did a rescan in a folder where the images where taken at the beginning of the May (and imported then). After the rescan all my RAW images had Camera Model "Canon EOS 600D" at the top level and not as they originally had "Canon > Canon EOS 600D". The rescan didn't change the JPGs.
Edit: Also the standalone camera model is now in lila.
