Jerrica,
Thank you for pointing that one out to us. It is actually accurate for what that nozzle represents. However, being an adjustable nozzle, it is the per degree flow that the system is calculating all placed heads at, no matter their arc. The value in the schedule should actually just be blank so you do not see them, which is what we are looking to get fixed up.
For now, you are welcome to run the schedule "By Group" instead of "By Nozzle" and the flows will not show up there, or you can simply uncheck the GPM column and hide that from the schedule entirely.
