No weapon mastery for "Dirk" weapons ?

[WayTooLongUsername]

There's a weapon type in the game called "Dirk" witch is a small one handed weapon that uses intelligence. But when I look at the weapon mastery it seems to be the only weapon type missing, all the other ones are there, sword, mace, staff etc. Would it fall under the "dagger" category or is there no weapon mastery for it at all ?

What i don't understand is that my weapon mastery reset on me after leveling it 5 times at least. It seemed to randomly go back to zero?

Is there any answer to this? I'm working on my Warlock and was wondering what Dirk may fall under if it doesn't have its own category.

According to people on their discord sever, dirks benefit from sword mastery.
