Different behaviour between desktop and phone - new responsive engine

Hi,
Can someone please explain to me why on my computer, my footer group aligns with the bottom left as I want it to:

But on my phone, it’s aligned with something that I can’t figure out what

I have put the page height in there to show that the two page heights are the same

Here is my element in the editor:

And here is the property editor showing the group is aligned with the bottom left

I have tried this on top separate phones (both with different screen sizes) and I have the same issue on both.
Is this bug?

Thanks
Paul

I have changed the minimum height of the slider bar element to 100% and now this issue has gone away.
