CSDM 2.1.2 - Problem with grenades
 

I am using CSDM 2.1.2 on my server. I am facing a problem - Players drop their grenade when they die. "weapon_stay" and "drop_packs" are set to 0. I tried downloading some plugins for this like noweapdropondeath.amx but no fix !
I hope someone can help me out ! . Thanks in advance.
Edit : I am using amx v1.8.1
