X-Axis labels duplicating when wrapped

Hi, 

 

Experencing some issues when using a report in the service. Some of the longer column names are overwriting themselves when they start to text wrap. 

 

Changing the width of the visual so the labels are diagonal fixes the issue, but when the visual is the proper width adjusting text sizes etc has no effect. 

 

Is this an issue anyone else has experienced? It seems like a bug.
