That same issue happen to me also [cannot select category]
Try to uninstall and re-install QTM [if same issue occur try the ff step below]
So I decided to do a manual upload here >>> https://www.gaytorrent.ru/upload.php
https://www.gaytorrent.ru/doupload.php
make sure to check private when creating a new torrent and copy & paste the url: Tracker >>> http://tracker.gaytorrent.ru:2710/announce
Seeding a Torrent:
GETTING THE .TORRENT FILE: You have to re-download the small .torrent file, not the data file(s) (typically the movie file)! The re-downloaded .torrent file will have your personal secret passkey inserted, that allows to identify you to the tracker. Do not use the .torrent file you created in Step 2 - It won't work!
