Odd seat maps and availability summer DFW

I've got a few flights booked long out into June and August, several of which have had odd seating maps displayed both on the App and online. One such example is flight 1660 on 6/29 out of DFW. The seat map in both Main Cabin and First are showing completely booked. I'm happy with my seat assignments, but am wondering what the heck is going on? I'm not on Expert Flyer, so I can't confirm seat bucket availability, but I'm shocked that two months out there isn't a single seat available on a 321. What's more, you can still book seats on 1660 (I know, not an indication of anything). Same thing for two other flights out of DFW later this summer for me.

Is this just another glitch in the system, or is something really odd occurring where the flight is indeed fully booked?

What is the destination? When I look at AA 1660, I'm getting PHX-TUS / TUS-PHX.

And do you have status? If you do not, then all of the elite seats will show as occupied, when they may or may not be.

EF flight details for AA1660 on 6/29 is showing DFW-PHX on a 321 dep 3:27 PM. J7, Y7. Seat maps pretty wide open there as well, but I can access elite blocked seats. AA.COM seat maps showing the same as EF.

Are you looking at aa.com or the app?
I sometimes get the "all seats taken" seat map on the website, when I can see the empty seats just fine on the app.

Thanks for the EF look up. It might be me, but I don't know how/why. Yes, I'm Plat with AA, so I can always see and access elite seats. Both the App and the website are showing all seats taken, both looking within my reservation for other seats to select and searching for a new ticket. I'll just chalk this up at an interesting glitch!
