You have the Display operator in event_003 disabled, but your Export Particles operator is in a global event (blue)...so those particles are not displayed, but they're being exported.
Put your Export Particles operator in event_001, then copy + paste it (instanced) into event_004. Then export - by excluding event_003 (and not having it in a global event) it'll only export particles in the events that you want.
