strange output when plex scans

[bayoumedic]

ACD mounted with RCLONE and ENCFS on top
VPS with 8 ram 8 cores

when running this command
$LD_LIBRARY_PATH/Plex\ Media\ Scanner --scan --refresh --section "$TVSECTION" --directory "$FOLDER"
it starts by printing out a bunch of UNKNOWN TYPE 7 and UNKNOWN TYPE 49 for a few minutes before showing GUI messages. What are these unknowns? This only happens when scanning TV Seasons folders and takes much longer than Movies. There are only .mp4 files in the Season folders. Here are example scan times.

08.05.2017 21:57:21 [PLEX SCAN] [ 39 ] /home/jason/plex/media/Movies2/The.Kings.Highway.2016.WEBRip.x264-Ltu
08.05.2017 21:58:31 [PLEX SCAN] [ 70 ] /home/jason/plex/media/Movies2/The Philadelphia Experiment (2012)
08.05.2017 22:11:20 [PLEX SCAN] [ 769 ] /home/jason/plex/media/TV/Gotham/Season 3
08.05.2017 22:28:31 [PLEX SCAN] [ 1031 ] /home/jason/plex/media/TV/Kevin Can Wait/Season 1
08.05.2017 22:35:51 [PLEX SCAN] [ 440 ] /home/jason/plex/media/TV/Outcast/Season 2
08.05.2017 22:45:49 [PLEX SCAN] [ 598 ] /home/jason/plex/media/TV/Supergirl/Season 2

So my question about this is, are these unknowns normal and are the scan times normal?
