If you are posting multiple files containing BBCode format [those are invalid fies], you need to remove those and redo your torrent ...
SEE : https://en.wikipedia.org/wiki/BBCode / https://www.phpbb.com/community/help/bbcode
also DO NOT create torrents with following symbols in torrent name: / \ " ' _ , !
These torrents will have problems with seeding on tracker!
