I can't see fix option in modal screen

Hello everyone! I’m new in Adalo, please bear with me…

I’m trying to create a modal screen with transparent background that I wish to appear fixed at the bottom of the screen but I can’t see the option to fix the rectangle in the “Edit Styles” section. I tried cloning the project available in Adalo Resources (How to Create a Modal/Popup Window - Adalo Resources) and in that project I can see the fix options but when I copy and paste the screen to my project, does options disappear.

Cloned project (with fix options visible):

Personal project (with no fix options visible)

Thank you!!

This issue has been resolve!

Thanks

Solution: Just had to configure the layout setting “Sticky while scrolling?” to “On”
