Hi,
Yeah, having a single tag triggering both groups would result in what you described.
As for the “update generally, then insert on trigger”, I agree. What you’re trying to do is fairly common, and unfortunately more complicated than it should be. The hour meter reset condition on the item helped a tad, but something like you described would probably help a lot. Until then, the insert could probably be done in a on-trigger action item (“if({tag}>0,executeUpdateQuery(…),0)”) to keep everything in the group, but again, I recognize that this is tougher than it needs to be.
Regards,
