Problem logging Event ID in Solar Winds

So I have something that's really puzzling me here, I have GPO Auditing rolled out across our DC's and I've configured Solar Winds to collect and tag events based on Event id. 

This is all good for group members being added, or removed along with a load of other things being captured, but for some reason it will not capture event id's relating to group policy, even though I can see those events in the event viewer itself, I  just don't get why. 

I've configured these under custom rules, everything seems to work but the the group policy stuff, I can there is pre-processing and postprocessing rules, I am not sure how they work and if the reason it's not working is somehow related to me not configuring anything in there?
