      Hi all,

         I met a strange about the time series collection . MongoDB version 5.0.18 and i create a time series collection with Expire property but when the time is come we see that document did not removed. Current date is ISODate("2023-08-17T06:53:03.288Z"), but you can see in the pic the data with timestamp ISODate("2023-08-10T00:00:00Z") was not removed and still exists. Who can tell me why
