Buttons disappear

Hi!

I am trying so hard to fix that… but after couple hours, nothing ;( Why my buttons are going far below once all the panels are “completed” at the end? How can I resolve that makes me crazy!

Hi Emillie,
I think you have missed adding a push/pull widget for the button.

Thanks,
