Issue with the slider

I’m working right now with the education mind basic theme and at the time i tried to activate the slider it didn’t work… i dont know if i’m missing something or not, but the same pages i’m using right now works with another templates.

I just downloaded both wordpress and the theme so i’m using the latest version of all.
Also i’m using PHP7 on my xampp control panel.

It’s a clean instalation, no extra pluggins or something like that
