Can not set evaluation time to "now" for chart

[pathfinder2104.work]

Hi,

I have four charts in my report and I can not set the evaluation time to "now" every time I set it even from the source(xml) it changes back to Group. How can I correct this ??? Or this is an correct behavior ? How can ask chart to load the data group wise?
