Render particle system using sequencer incorrectly

Hi,guys!I’m a beginner in UE4.I have a ice effects with particle system.When i want to render it as a demo with sequencer,i found that the particle system rendered incorrectly.All the particles which should be spawned after the collision didn’t render out.But it shows correctly in viewport and the camera in sequencer.I have looking around but i don’t know how to fix it~I post two pictures here,the first one is particles in camera,the second one is particles rendered out with sequencer.THX!

I found that Increasing the collision distance can solve this question…
