Last Datadisc

I’m trying to completely 100% Jedi survivor, and all I have left is one datadisc but I’ve completed all the planets, and with the treasure upgrade it’s still not showing up. When I click “show on Holomap” it pans the camera to a random area on Koboh, I’ve checked many places around and I still can’t find it, I’m not sure if this is a bug or if I just can’t find it. Has anyone else had this issue? (I already got the one in Holotactics)
