Leadership not working?

[Jeava]

Hello all

I just mastered sailing this evening, and found out something interesting. One of the skills I have on my radial for sailing is "Leadership: Temperaraly increases refresh rate for cannons, broadsides and sailing cool downs" (not word for word, but as close as I can remember to the actual discription.) I have a point to spend, but I'm not allowed to take the skill. On my radial there is, and has never been a level restriction, and it seems I should be able to put a point in it. But apperently I can't? Is it broken, taken out of the game? Any help would be appreciated, thank you
