Cannot train crew skills

I have preferred player status with a number of characters of varying levels, all of them with crew skills. I recently made a new character and it will not allow me to train any crew skills. When I right-click a vendor an empty box pops up, and my only option is to 'cancel' and exit. I have the mission to learn a crew skill and interact with vendors, but it says it's appropriate for lvl 55 players?

Can anyone help?
