The best place to start is in the Tablo Ripper config, Add Metadata. Try de-selecting it. @CylceJ posted about this a while ago: Tablo Ripper - Automatically download new recordings - #751 by CycleJ
Your MCEBuddy custom renaming for the TV Show conversion task is a bit different from the guide. It doesn’t look like the files will be put in a directory for each show and season. Not sure if that is important to you.
Enable Custom File Renaming (from the wiki)
%showname%\Season %season%##%showname% - S%season%##E%episode%## - %episodename%
If removing the add metadata option doesn’t help then try this next (still with metadata turned off). Go into Expert Settings in the Conversion Task (the button is between Save and Cancel).
Expert Settings (from the wiki)
Download Information: checked (Expert Settings > Media Information Management)
Add Information: checked (Expert Settings > Media Information Management)
