Upgrade List on DL iPhone App

I know the DL website has had issues with the upgrade list since the redesign, but now I'm seeing something peculiar in the otherwise reliable DL iPhone App...

Flying DL87 JFK-LAX tonight and while the iPhone app and website have me in the same position (2 out of 10,) the website shows 8 seats available up front while the app shows 0. EF corresponds with the website, showing J9 and at least 9 free seats on the seatmap. I assume the app is wrong in this case (that there are 9 seats up front available for upgrade,) but was curious if anyone had further insight or has seen this issue before.

Thanks!
