Am not entirely sure what you are asking. The aggregations that approximate tend to be off by small percents (1-5%, etc), not missing whole sections of data. I'd guess you are filtering wrong, or maybe kibana is hiding a partial bucket due to timepicker or something? Any more logs, screenshots , versions - to give more details on this ?
Cheers
