Data returned by querry get's rounded down for a specific field only BUG

Data from elasticsearch (datasource) - from metricbeat 7.11.1 get’s rounded down only for system.cpu fields. System.cpu.total.norm.pct for example returns a number between 0 and 1 which represents the load of the CPU normalised (for the number of cores). In a graph it gets rounded down (to 0 of course) and the System.cpu.total.pct (not normalised) also gets rounded down but you can see it rounded (1/2/3/4/5 whatever the load is at the time). Other fields work and they are in the same form, a number between 0 and 1 which doesn’t get rounded.
Also, in the raw document it is reported ok, not rounded.

this is from the explore tab, as log


what is shown in the picture is that my computer’s cpu load is 6% (at the time)

and this is from the explore tab, as a metric

Why is that? Why only for the CPU it is rounded?

Couldn’t attach the working examples because I am limited to 2 media attachements since I am a new user.
