ColumnNames are not translated (no replies)

Hi

I have problem.

Use API Actions.getPageUrls. format CSV or TSV.

http://demo.piwik.org/index.php?module=API&method=Actions.getPageUrls&format=CSV&idSite=7&period=day&date=2015-05-05,2015-06-03&label=&date=2015-05-05%2C2015-06-03&filter_limit=false&disable_queued_filters=1&format_metrics=1&expanded=1&translateColumnNames=1&language=en&label=%40%252Findex

ColumnNames are not translated.

Date,Label,0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,Avg. time on page,Bounce Rate,Exit rate,Avg. generation time,Metadata: url,Metadata: segment,15

Thanks.
