dark side tank revive datacron bug

Hello! I use my arena team (LV, royal guard, maul, piet, vader) with datacron dark side tank revive ability. But if cat use her ability force leap first time in my royal guard instant kill it, but the dc revive cannot work. (If i use sith empire team with Malgus against the same team, the revive works with malgus after cat insta kill.) Please investigate the error. (Sorry for my english)
