Proc chain auto delete of overlapping requests not working.

I have added the process to delete overlapping requests of full data loads to a cube, in a process chain. The previous packages are not being deleted when the process chain executes. The process chain messages indicate 'no requests for deletion were found'.

However when I run the same info-pkge with the same criteria independently, the previous loads are deleted.

Am I missing a setting somewhere?

Thanks for your time and assistance.
