Updating TVShows, tvshow.nfo found in root problem

When updating TV shows, TMM is producing the error “Found file ‘tvshow.nfo’ in the root directory of the data source. To get this imported, move it to its own directory!”
This looks to be coming from TvShowUpdateDatasourceTask2.java at line 195 however it’s not producing enough information for me to establish the cause of the error.

It would be helpful if the error could also log the full path so I could investigate where this is coming from. Nothing appears to show up in the log files to help diagnosis.
