Dynamics 365 For Sales Search gives incorrect result

Hello Experts,
for Dynamics 365 For Sales Search snaps give result incorrect result .
i applied greaterThan criteria for filter condition. still it work like "greaterThanEqual to "

why i'm getting data for '2023-12-18T08:15:18Z' as i have selected greater than option it should not give this record.

Any suggestion what i'm doing incorrect.

Regards,

Ajay
