Two different values on one column on barchart

I have one bar chart on Grafana (using postgres). Values (count of views) shown on columns of bar chart are correct, but hover tooltip shows two different values of adjacent dates (example on screenshots).

As seen on screenshots, when I move arrow to the right, hover tooltip shows correct value, but at the left side hover tooltip shows the value of the previous date (both values on one column).

How to fix it? How to represent one value per one column (i.e. per one date)?

Screenshots are below:

Date 28
