rescheduling publications creates a new recurring instance

Hello,

I have a problem when I try to reschedule a recurring scheduled instance of a publication (source is a WebI report).

When I try to reschedule the instance and chose "Replace existing schedule" it always creates a new recurring instance and the old one stays.

I'm on BO 4.0, Servicepack 5, Patch 9.

Anybody some advise?

Thanks a lot.
