Same here regarding *arrs handling the data movement/layout and nfo files. I even have the "Connect" sections for each set to trigger rescans, but it seems especially for files that get replaced by a more optimal version, a duplicate is left over in kodi alongside the new one which only goes away when you try and play it. I tried switching to a dedicated mysql instance for shits and giggles, no effect. Some day I'll actually dig in the logs.
