Atmos icon not displayed

Hi all, I’m having an issue with Kodi 21 stable on all installations (FireTV / nVidia Shield / Windows 10). I’m using the latest v5 version of TinyMediaManager to scrape and save all metadata locally for each title in my movie library. The NFO created by TMM for each movie contains all information required (eg. resolution, video codec, HDR format, audio format, etc) and when I scan the movies into Kodi 21 using local information it generally now shows the video details for each title. There are a tiny number of titles, however, where Kodi doesn’t seem to pull the audio format from the NFO, even though it is there. For example, I have the NFO for “10 Cloverfield Lane.atmos.bluray.mkv” showing that this title is sourced from a Bluray, is encoded using the H265 codec and contains an Atmos 8 channel track, but when I highlight the movie in Kodi 21 it shows all metadata details but the audio shows “” instead of “Dolby Atmos”. Is this a known issue and, if so, is there a fix?
