Display duplicate task item when scroll

CoverByNguyen

I have about 500 tasks.
The first, I only show 30 tasks. When I scroll down, I will call api to update task list.
Each api called, I added 30 task to task list.
But after call api and task is added to task list. If I scroll up/down continuously => occur duplicate task same task id.
Please tell me root cause this problem

I checked tasks data in api.getState()
It return correct. But on screen it still display duplicate task(this task push on top)

I see that this library is using Virtual scroll technique. I see that -> when issue occur, duplicate task is buffer task in Virtual scroll. Maybe it relate to buffer task????

Hello CoverByNguyen

Could you provide your code of how you implement adding tasks so that I could investigate the issue?
