Did you get a message saying you couldn't join after you clicked the join button, or were you unable to join despite clicking join? I understand that it's showing Limestone instead of Avila, but it also has the join button which only shows up when it's time for territory war. Otherwise it would say "started" or "ended".
Showing the wrong territory could be a glitch or something, but I'm not seeing anything in the screenshot where the system is telling you that you cannot join the territory war, which should be displayed in your chat window after you clicked join unless you turned off system messages.
Also [GS]Lixy, I don't know if you made that document but in case you did, while I can tell the All-Inclusive EE Schedule is in PST because it's 3hrs behind my time, it should still be made note of in the document for those who can't tell by cross referencing when things happen for them and when it's listed in the schedule.
