Flink Metrics Web UI don't show double value

How can I see double value in flink web ui on dashboard? Maybe, it's possible with something configuration?

When I tried see metrics, like Meter, on dashboard view only the integer part of number. In log I can see double value:

File with Flink config: https://github.com/dedkot01/busting-grain/blob/master/local.conf

If u want run project, just use command in project directory sbt pipeline/runLocal

If it's not possible in Flink Web UI, where it's possible? (maybe in Grafana?)
