In my network profile I'm seeing what I believe are irregularities in the HGL of my laterals. For my network, my design is utilizing a trunkline running down one side of the road with six inlets on the opposite side connected to the trunkline with laterals. Two of these laterals appear to be function properly, in that their downstream HGL elevations are within close proximity to the HGL elevations of the trunklines that the laterals are connecting with. But for the rest of the laterals, the HGL elevations aren't even close. They are displaying a relatively low HGL as if there is no water in the trunkline they are connecting to. I even tried deleting my entire network and re-creating it with no luck.
What could be causing the other four laterals to not properly display the backwater effects of the trunkline's HGL?
