Long story short, I booked a flight through my corporate travel tool (Amex/Concur). Somehow between there and delta.dumb my name changed from first name middle name last name to adding my middle initial to my first name and then my last name. My understanding from numerous threads is that this will cause me to lose precheck even though I have my known traveler number in the system. I called delta and they assured me there is no problem. Should I hang up call again to try to get the name corrected?

Thank you
