Hmm 🤔

Are your groups overlapping each other or stacking on top like legos? See example: [Understanding Vertical Scrolling Elements in Bubble - #8 by J805](http://forum.bubble.io/t/understanding-vertical-scrolling-elements-in-bubble/92674/8)

Make sure your groups stack down the popup so the popup is longer than it should be, just make sure collapse height when hidden is checked. 😊
