Heatmap Visualisation does not show zero for empty aggregation

Elastic Stack Kibana

I'm building a heatmap using the Metric aggregation "Count". Sub-buckets are added: one for Date Histogram (with 1s interval) and another for Terms (hostname).

I have added {"min_doc_count":0} for the JSON input of the Terms sub-bucke(hostname), but I am still seeing some empty buckets.

I am trying to understand why not all the empty buckets are not being assigned the value of "0"...

I just tried this in my local and I am wondering at what exactly you want to see?
I am seeing the empty buckets. But the zero is not getting displayed on the tooltip.

Is that what you would like to see?
