ERAC: filters do not stick

I'm a newbie with NOD32 4.2BE and ERAC. One thing I cannot figure out is how to make filtering "stick".

e.g. in ERAC I am looking at the clients tab and right click a machine and choose Data for this client->Threats. It switches to the Threat Log tab, applying a filter for this particular client. Great - just what I wanted - top be able to see threats on just this client. Now the problem: if I next click on one of the other tabs (e.g. Event Log), the filter criteria change. The criteria is either all cleared, or retains data from the last time a filter was set on this specific tab. Why doesn't the filter for the current client machine stick when moving from one tab to the next?
