Sum up - results are partly not shown on filter results gadget on Dashboard

[Roger Biaesch]

Hello there, 

I want to sum up filter results on a dashboard with the sumup Addon for JIRA Server.  Somehow it works on my system dashboard, but not on any other dashboard I create (the sum row ist not shown below the filter results) 

I can see no differences between the filters, or the gadget...

Do you have any idea what could be wrong?

thanks in advance  + best regards

Johannes
