Can someone help me understand what this means?

I have an upcoming flight. Homeairport -> ATL -> LAX -> AKL. 3 legs.

I called and got GUCs applied.

The trip on Delta.com is now showing *5* segments, with the ATL->LAX doubled and the LAX->AKL leg doubled.

LAX->AKL leg is showing the same flight number, twice.

First is showing comfort+ and the second is showing D1, fare class “OK.” I can’t select any seats on any segments anymore. (Same for ATL-LAX but different fare class)

What’s “OK?” Does that mean the GUC is clearing? Do I need to call in to make sure everything is applied properly?
