Dark-Split sword completion?

[--BAT--]

As you can see I've completed both forms, but on the "Show profile" page under "Melees" or "All" The sword itself is left unfinished yet I have used and maxed both forms. Any idea how to max out the grayed out stock dark-split sword? or is it just bugged for now?

 

--- Edit, Known glitch confirmed on the Trivia page via the Warframe Wikia http://warframe.wikia.com/wiki/Dark_Split-Sword Still, anyone know if it's possible to max out or at least grab the attention of a possible fix for this? I'm a completionist and getting new weapons for the mastery and all is what I love doing. Would hate to have this stay grayed out

A ticket was raised and they are aware of this. Annoying though!

It's just bugged right now. I'm still waiting for a fix, but it's been like this since the dark split sword was introduced :(

It's just bugged at the moment, you can't max the sword itself.
