Kibana 4.5 - New feature CustomLabel

I seem to have a bug on the use of CustomLabel.

When I put a CustomLabel on a metric, it works .


But if I add a "split lines" Filters, labels disappear from the graph :

And Do you know if it's possible to put a CustoLabel on a filter. In my example, I want to rename "PEROIODEJ:MardhBatch" with "Mard batch" ?

Thanks!

@pittoch

click on the label button (see blue arrow)

Thanks!
The problem is solved.
