Chart: datetime created_at bucket MONTH does not work

version: 2021.3.10
source: docker image

A chart using created_at as dimension with a bucket function of MONTH does not show any data although data exists for previous months. Function WEEK works fine.

This can be reproduced in the default crm namespace on LeadsPerMonth chart.

Thank you for the report, will try to reproduce and fix

I tried to replicate on LeadsPerMonth, but it works fine for me. Both on MONTH and WEEK buckets.
If possible, could you export your chart ?

Is it possible that you don’t have your y axis start with 0 ?
