How to create an "only integer" Y axis

I am using Grafana 8.05 to plot some data from SQL Server data source.
I am using a Time Series Panel to plot Integer (bigint) data.
If the values span a short range, for example 1 or 2 between minimum and maximum value on the same plot, the Y Axis shows decimal numbers, and this is not correct because the data I have are all integer.
But if i set Standard Options->Decimals = 0, the Y axis does not show me any more the decimals, but duplicates the unit without decimals, and this is not appropriate:

How could I show on the Y axis only “3” and “4” ?

That looks to be like a bug

The way for now to get by this “bug” was to change the Axis/Scale to logarithmic
