The tab that displays the leveling tree and the rewards from leveling is conspicuously absent, replaced with the tab for naming your character and giving them a biography. I've noticed the latter tab has also inherited the former tab's name as it is called Career even on the bridge officers.
Append: After trying out the new tailor interface I think I might have an idea what's going on. The game has flagged player characters as bridge officers, thus removing the display of the leveling tree and restricting players to wearing only uniforms. At present it's the only thing that makes sense.
