Can’t start battle in “Jedi Knight Cal Kestis” Hero’s Journey event

Hello,

I meet all the requirements for Tier I of the “Jedi Knight Cal Kestis” Hero’s Journey (7 stars, Gear Level XII, specific unit, recommended power exceeded), but the battle remains locked and won’t start. There’s no error message—just a “Battle Locked” button. My character is level 85, all abilities are maxed (except the unique ability, which is at level 7), mods are equipped, and all required conditions are shown as fulfilled (see attached screenshots). Please look into this issue and help me unlock the battle so I can progress in the event. Thank you in advance!
