SEP 12RU5 GUP loop

hi guy

i troubleshoot some GUP are not up to date, when i open system log i see this error ( see picture ) , this client is GUP and it request download new content update from itself , look like this GUP is loop , because i put  the GUP and client ( in same subnet ) in a group that have same LiveUpdate policy , is it need to put the client and GUP in 2 separate group ( i mean client have live update policy that define GUP is which IP and GUP have live update policy that direct go to SEPM )

because i put the GUP client and client in same group in few year ago and it working fine , but when upgrade to 12 RU5 too many issues with me.
