Dwight, congratulations on that first flight
About the spine and leading edge spars, I am not familar with HQ deltas specifically but very familiar with deltas in general.
I am surprised that the sleeves are open on the ends. Typically what I have seen is that the spine is full length and the LE spars are short. For storage you slide the LE spars to the nose and roll or fold the kite up, for flying you slide the LE spars down the the wing tips. Even with this it is not unusual for the LE spars to creep some during an extended flight.
Did you purchase from a local shop that you can check with?
