Custom arrow deals the wrong damage

This is my 1st go at modding ark and i am trying to make a more powerful arrow.
It works fine with the bow but not the crossbow.
In the dev kit it consumes and picks up the correct arrow but in game it deals less damage than a basic stone arrow unlike the bow.
The bow and stone arrow deal 55 damage with my arrow it does 80 but with the crossbow the stone arrow does 95 and my arrow still does 80.
Any ideas ?
