Quota Policy per Month acts as per Day

Create organization, create plan, add Quota Policy 1.000.000 requests per ClientApp per month for this plan.
Create API, create Client App, create contract using the plan.
Make a request and inspect the value of X-Quota-Reset HTTP Header in response.
In my case the value in seconds after midnight:
X-Quota-Reset:"86095"
which corresponds to 24 hours.

Observed:
At the nearest midnight the value of X-Quota-Remaining is reset.
The value of X-Quota-Reset is incorrect.

Expected:
X-Quota-Remaining should be reset only next month.
