[2022] DZ South Recon Mission Locked

I didn't do any DZ content until end-game, but now finally decided to try it out. I went to complete the DZ East Recon mission, which had me input recon data, then the gate opened and the mission completed by the time I got to the checkpoint. I can enter DZ East and play, but I'd like to open the other 2 zones. Unfortunately, when I attempt to do the DZ South Recon mission, it says that the East Recon mission is required, but I thought that mission was completed.
