Why does my crystal betrayer have orb skill

Hi I have a dedent dagger crystal betrayer and it has orb as the main hand skill. It did not used to and other daggers don’t have thstb skill eight the same gear. I’ve tried switching all of my gear and nothing and I want daggers not the dumb shakarh or what ever even though I think I have near perfect one. If anyone else has come a crossed this problem let me know. I’ve even tried deleting all the stats and rebuilding it but nothing and it just has DMG affixes

u can change mh special skil using amber.
(maybe unaccidentally use amber on it).

That must be it. Thanks
