TSA-PreCheck not showing on Delta boarding pass

I received TSA precheck via NEXUS (or at least I presume I did since it's included with NEXUS) over a month and a half ago, and added the KTN (Known Traveler Number) to my Delta Skymiles profile. I booked my Delta flight after this was added. Today I checked in 24 hours before my flight but could not see TSA PRE on my boarding pass. I called customer support and verified the name, number and other details and it seems to be matching.

The only difference I see is that my first, middle and last name (say X, Y, Z) is Given Names: X Y, and Surname: Z on my NEXUS card whereas on my Delta profile it is First Name: X, Middle name: Y, and Last Name: Z

Is this enough to throw off the TSA database into not issuing me a pre-check boarding pass?

I cannot change any information 72 hours before flight so I will try at the check-in counter again, but has anyone faced this issue and resolved it?
