Sorry, Diceman, I didn’t see this when you originally posted and since you appear to have a ticket open at the moment on this…
You’ll want to also go to see Highlord Darion Mograine outside of Stormwind Keep. He has the quest “A Chilling Summons” for you. You might want to turn on Trivial Quest Tracking. If you don’t have it on you won’t usually see a low level quest, which is what that Shadowlands quest would be if you are level 60.
