Un-augmentable Knife

I asked in Global but did not elicit a satisfactory response concerning this issue, so I am taking it to the forums to gauge how widespread it is:

Several months ago, I tried to apply an augment to a Gazluk Keep knife I looted (to no avail). I kept getting an error message saying the item doesn't have enough enhancement points, but unless I am mistaken it has a full allotment of them. The item has never been augmented before, only the mods were transmuted a few times and repaired maybe twice. Still, it will not take the augment. I have included screenshots of the item stats and error message.

I have applied knife augments before, and I believe it is this particular "Gut-Ache's Chopper" that might be bugged, although I currently do not have another to test with. Please let me know if anyone else has had this problem as well.

Thanks.

It is an item that is missing it CraftPoints line, if it was intention I would think it would have the line but a value of 0. Probably just an oversight, I made a detailed report in game.
