Page Overlay error while using period=range (no replies)

Hello,

I would like to use "Page Overlay" with more than the current year (this is the longest period which is selectable with the period selector). That's why i modified the URL in this way:
... period=year&date=today ... -> ...period=range&date=2012-07-17,2013-03-22...

It looks like the values in the bubbles consider the new period but i got the following error in the left frame (where usualy the "Main metrics" are displayed)

The date '2012-07-17,2012-07-17,2013-03-22' is not a correct date range. It should have the following format: 'lastN', 'previousN', 'YYYY-MM-DD,YYYY-MM-DD'.

I didn't wrote "2012-07-17,2012-07-17,2013-03-22" but "2012-07-17,2013-03-22"

I also tried lastX and previousX but also got an error.

Best,
