Pitech Slider not working

After i installed the pitech template, i wanted to use the originally pitech slider which is good looking. After i tried to work on it in dekstop view, it instantly disappears after i edit anything. When i change the view mode to phone, it appears back in desktop view but it isnt visible on the real website. So the slider appears and disappears all the time in SP Page Builder. Someone please help me with this issue or fix the bugs over pitech template fast.
