QoS-Smartview Monitor - QoS Interface not defined

[detsh]

Hello,
we have QoS active on our NOKIA/Checkpoint NGX R62. If we want to see the actual traffic with SmartView monitor, what meets QoS, I can only see 'QoS Interface not defined'. I found an article from checkpoint, who meets this problem: sk31407. I followed the instructions:

detach the clustermembers from clusterobject
save the policy

tried to attach the clustermembers. I got this message:

'The Gateway cannot be added to this Cluster since it's used in places where Cluster members are not allowed.'

What can this mean? (I do an database revision restore, to get my old, but functional config.)

Many thanks for ideas.
