Niagara keep looping unexpected

My particle works well in 4.24, starts after 0.45s, loop for 3s, then stops.
However last night I sync to 4.25 and noticed this new Emitter State, and the emitter keep looping forever.
Here’s the emitter setting:
LifeCycleMode: Self;
Inactive Response: Complete;
Loop Behavior: Once;
Loop Duration Mode: Fixed;
Loop Duration: 3;
Loop Delay: true, 0,45;
Scalability Mode: Self, all false.

I also noticed no matter what kind of emitter I’m using, as long as the LoopDuration + LoopDealy >2s, the infinite loop will happen, and it doesn’t matter if I enable LoopDelay or not. If it’s <=2s, it can stop.

Can someone help?

I had a same issue in 4.25 last year. I using 4.26 now and I think no more happens. I tried to find bug fix in release note, but I could not. Have you tried in 4.26? And it’s not happens?

loop delay subtracts from loop duration. if you want 2 delays and 4 duration then the duration should be 6.
