What output do you get if you run the ffmpeg command that replaygain runs?

ffmpeg -nostats -hide_banner -i "/home/max/nas/media/music/albums/Mefjus/FabricLive 95_ Mefjus/01 Decypher.flac" -map a:0 -filter ebur128=peak=true -f null -

I found out that it's actually the edit plugin that will write empty rg_ tags to the files when opening --all fields, as we can see:

  genre: Drum & Bass -> Drum & Bass; Electronic
  rg_album_gain: 0.0 -> 0.0
  rg_album_peak: 0.0 -> 0.0
  r128_album_gain: 0.0 -> 0.0
