Solidworks PDM 2017

We have a PDM server at our home office, replicated to another site.  We're running out of disc space and are in the process of cleaning things up a bit.  We're seeing an increase in available space after the clean-up service runs on the server at our home office.  However, we don't see a corresponding savings on the replicated server.  Any idea why this would be?  We really need to get this problem solved quickly.

Thanks,

Eric
