I'm having a porblem with leveling my strike characters to SA 15. I have two dokkan awakened King Vegeta strike characters. One is at SA 10, the other is SA 5. However, when I one to train the super attack to 15, I can not select the other in the training partner screen. You can see it in the screen shot provided. The training partner is simply greyed out. I have even tried bringing the training partner to UR statue, and it still does nothing. All of my strike characters are doing this. Anyone know why?
