InfluxDB showing values for a timestamp only when a particular time range is selected

InfluxDB query shows non_negative_derivative value for a timestamp only when a particular time range is selected.
Eg: start_time = 19 March 2021 01:41:52 UTC ; end_time = 19 March 2021 01:43:20 UTC ; timestamp = 1616118120000000000 shows non-zero value
```
SELECT non_negative_derivative(max("http_response.5xx"), 10s) FROM "haproxy" WHERE "host" =~ /host_name/ AND "proxy" = 'proxy_name' AND time > 1616118112000ms and time < 1616118200000ms GROUP BY time(10s), "proxy";
name: haproxy
tags: proxy=proxy_name
time non_negative_derivative
---- -----------------------
1616118120000000000 2113
1616118130000000000 0
1616118140000000000 0
1616118150000000000 0

1616118180000000000 0
1616118190000000000 0
```

When a slightly earlier start_time (2s) is selected, the same timestamp shows zero value.
Eg: start_time = 19 March 2021 01:41:50 UTC ; end_time = 19 March 2021 01:43:20 UTC ; timestamp = 1616118120000000000 shows zero value
```
SELECT non_negative_derivative(max("http_response.5xx"), 10s) FROM "haproxy" WHERE "host" =~ /^p-allocation-service-haproxy/ AND "proxy" = 'allocation_service' AND time > 1616118110000ms and time < 1616118200000ms GROUP BY time(10s), "proxy";
name: haproxy
tags: proxy=allocation_service

1616118180000000000 0
1616118190000000000 0
```

The logs corresponding to this metric do not show any 5xx during this time range. Hence, not sure of how the value spiked up to `2113`.

Any idea on when this kind of behaviour will be exhibited?

**Environment Info:**
VM: Ubuntu 16.04.3
InfluxDB version: 1.4.2

Reproduce both InfluxDB queries on the reported 1.4.2 environment, changing only the start time, and compare the derivative output at timestamp 1616118120000000000. Trace the query and non_negative_derivative behavior involved; done means explaining the discrepancy and providing a regression test or clearly documented expected behavior.
