Android remote listing failures

I have a T95Z settop box running Kodi 16.1 to play audio & video media files from a LAN server through an AV receiver. I’ve no need of Kodi library functionalities. Kodi looks at a LAN media server with, mostly, classical music & opera files, audio & video listed separately & alphabetically round period, composer, title, performers, encoded entirely in folder and file names. With some help here, I managed to find Kodi settings that ensure Kodi displays just the filenames and not other info.

However Android Kodi-remote apps like Kore, also Yatse, make huge errors in listing these files and folders. Under “Files”, Kore (and Yatse) display skips some folders altogether, and add in file entries from other folders. I don’t see a bug reporting page for Kodi, so I’m asking here, how do I get round this?
