This looks like unexpected behavior. Would you like to share either a copy of your app or the blocks that you use for that screen. Also, you may want to report this on get hub if it is a bug. When bugs are reported the admin‘s are able to take care of them!
Hi @kartik14, thank you for your suggestion, it is an interesting workaround. I added a row component at the bottom of the screen with absolute size 25 px, and set the margin to -25 px (in my case the space of 12.5 px was doubled).
Although it is not the ideal solution, I am happier now with the app, so I will mark your answer as the solution. Thanks again!
