Sabrina Hock's dashboard

Hi,
I've got a problem with my reporting functions. I'm reporting on pages having a special label over all spaces using
{code}{local-reporter:value:label Foo > label:content}{code}
It worked fine until I reverted one of the pages to an older version. Now all old versions of that page using the label are shown in the report-list.
Any ideas how to fix that?

thx
Sabrina
