Master Detail Reports not working as expected

Ibag

Hi,

I have a requirement to build a dashboard with 4 different reports, first 3 of them are bar charts and one pie chart in the last. My first report is a master report for next 2 bar charts(reports) and those 2 reports are master events for last(pie) report. Pie chart is working fine and listening to master event, but I am unable to pass master event from my first report. Interaction between 1st and rest of two not working.

Any suggestions would be appreciated.

Please be noted that they are 4 different reports and not views.
