Delphi 10.1 Berlin :: Form Inheritance and Layout.Padding Bug

Simple FMX app having base form with a Layout.padding set to (20,20,20,20) and a few inherited forms.
Few of them have different settings for padding, but changed, saved and reopened: 

Changes are not saved, I checked the *.fmx file !

So do I really have to set each Layout’s padding individual by hand ? Per platform ? Oh boy this is crazy !!!
