Server does not remove deletion stubs

Hi, each night I remove and import an amount of docs. It all works fine, but the removal leaves deletion stubs. I set the replication parameters on the “Space savers” tab to 3 days. The updall-V process should then each night (1/3 of 3 days) determine if there are deletion stubs that need to be removed. However, it doesn’t…Anyone an idea why the deletion stubs are not removed properly?

I know there is logic that removes docs without leaving deletion stubs, I don’t want to use that. I know there is logic that removes deletion stubs explicitly, but that seems to work only fine on 32 bits environment (we run 8.5 64 bits)…
