When editing tiles in a theme there is the option to adjust the header/footer size on individual tiles.
Is there a way to see your custom size when you go back in to edit a theme?
Right now all it shows is Custom and to change it again I have to select a size then select custom and guess at what size I need.
Thanks for reporting. I’m looking into it… 
Edit: I’ve fixed this in my development instance and we will include it in the next beta release.
The fix for this was deployed to beta this afternoon.
