Standalone Button Font Bloat

[Mark Swindell]

What's the trick to maintaining the correct font size for buttons in
substacks using when building standalones?  When everything is all one
stack, things look normal, but when using a splash as my main stack and
placing substacks into a data folder, my substack buttons suffer from
bloated labels and I can't find documentation to address this, nor do my
attempts to alter settings in the standalone builder.

Building for MacOS this time around.  Thanks for your help.
