Code:

ERROR: NEWADDON Unknown Video Info Key "progress"
ERROR: Previous line repeats 24 times

This happens everytime with SH (through metadatautils) on any machine, polluting the log.
You haven't noticed that on ur end? 

As far as i know " unknown video info key progress" is related to a button placed in a focused layout .
(E.g. a hidden button with onfocus action)
Kodi tolerate it, but button isnt supposed to be there   

@mardukL can u elaborate? I don't see how it could be related though...
I tested removing the key&value of progress from infolabels dictionary (line 398 in kodidb.py of metadatautils) and it seems to eliminate the issue, but not sure of the consequences yet.
I just can't find any instance of using this key in the code or the related addons...  

 Maybe im wrong, just remembered read it somewhere here.

could also be related to an to kodi unknown info label. 

Some reddit post: 

Those are meta info passed to the kodi infolist items such as movies/shows/episodes so that you can see plot year rating and other additional infos. In some cases a dev can decide to pass additional infos in the meta not related to the kodi infolist but that might come useful later on in other addon functions like additional ids or links. Thats nothing to worry about and it doesnt messes up your setup, its jist kodi telling you it is unable to show those unknown infos
