Vray RTX keep rendering in loop by Deadline

So I’m using Max 2020 with Vray GPU 5 update 1.3
I can send job and Deadline can handle and render the job
But whenever I’m in RTX mode then after it finished all frames,
It starts again and seems can’t get out of that loop and stuck at 1 job forever.
Because I only have 1 machine so I set the chunk to 999 frames.
