fapi returns wrong result. especially volume and trade count if I snapshot every hhmmss.0 and hhmmss.5

API Futures API

Hi.
I am trying to get data from fapi every hhmmss.0 and hhmmss.5(2 times every 1 sec.) and I call ‘/fapi/v1/klines’ endpoint with 1 day interval.
The trade count and volume may return a smaller value for a timestamp that is newer than the previous timestamp and this is I think wrong returns.
How can this problem be solved?

this is my snapshot.
And this shows that sometimes the api returns previous state.
