Spawning in a gun causes "SWEP:SetWeaponHoldType - ActIndex[ "" ] isn't set!"

So this has been happening to me for a while, whenever i spawn a gun, this pops up in console “SWEP:SetWeaponHoldType - ActIndex[ “” ] isn’t set! (defaulting to normal)”
Even though it spawned in my inventory and not my hands, it pops up. Im using M9k and Sleek weapon and it seems to occur for both weapon base.
The gamemode that i’m running on is DarkRP

you should google your problems first

i looked at that post and had no idea what they were talking about. But i figured it out. Thanks for replying though
