Clutch problem please help

I recently bough an integra 96 gsr from a friend. it has 160k on it. What the problem is that i can't get a smooth start on the first gear. Like, every time i start my car from first gear, it jerk and seem like it wana stall, the clutch is not gripping probably. after that 2nd, 3rd 4th...gear its fine. I replace the clutch 6month ago and i dun understand whats causing this jerk in first gear, no matter how slow i try to release the clutch padel, it still jerk. Can someone help me with a solution to my problem?
