I was able to rescan for metadata from the edit rom context menu if I remember correctly.  Thanks for looking into the the steam thing as well.  I started kodi the other day and noticed I now receive an error message about one of my launchers.  The same error message tells me to report it as a bug so here is a log.  https://pastebin.com/sFh9bEUb

Please disable Kodi debug in Kodi settings and enabled AEL debug in AEL settings. The log is very difficult to read because Kodi Debug is ON and the amount of information is overwhelming. Once you upload a new log I will have a look at the problem. 

Here is a new paste, thanks https://pastebin.com/z5b5Bb90

OK, I can see the error now, however I cannot determine what caused it. Can you please post the file KODI_USERDATA/addon_data/plugin.program.advanced.emulator.launcher/categories.xml? You can find the KODI_USERDATA directory here.
