Battle set up disappeared.

[Gandamula]

I found a weird situation, I never like it to much, I prefer the former attribution of battle groups in the party menu, but now in a new game, I noticed that the initial set up in battle maps disappeared, I simply start a battle in the old way, the problem is that I even can set the groups in party Screen. It was any key that I touched without notice?

Do you have more than 20(?) troops? With few troops the UI does not appear

To be true, I noticed it when I was ten soldiers,I don't remembered the previous game, I just jumped form 1.6.4 to 1.7.1 last week.
So ,if that is the answer, shame on me. Anyway , thank you.?
