SEPM periodically deletes all GUP server IP addresses from globallist.xml

Hi,

Could someone please explain why the SEP management server removes all IP addresses from the globallist.xml?

This happens every week and is giving major issues as the GUP servers stops serving as a GUP.
We have version SEP12.1 RU1 and have configured the Live Update policy with multiple group update providers.

Strangely enough the GUP server self is downloading from the GUP even when it appears to be false in SEPM.

Kind regards,

Rogier
