rogue trainer missing poisons ui bug

been having an issue when using the rogue trainer to buy skills

the poison category either isn't visible or only shows one of the available poisons to learn until you buy another skill at which point the rest of the options appear

not sure if game or add on related, may just be an issue between 3.3.5 addons not working with onyxia but thought I would bring it up in case it was a game bug

not exactly game breaking or anything just an inconvenience especially if you are only there to buy poisons
