Tracker reports and graphs with values 0.0 got prepended by dhis2 data element id

Using dhis2 2.24, revision 84f27fe, when my events values contain 0, the display is weird.

The data element id is prepended to the value.

The analytics api result looks ok containing “0.0” and “1.0”

When exported as xls or html, nothing is preprended and get only the “0” as expected

When displaying the individual events the display is ok.

The data element is defined with true

Am I missing something ? or is this a UI bug ?

Thanks for your help,
