Line are jumping in different styles because of missing "Export STAT table"

[usted]

Hi there

I'm having the issue that the height change between the styles even though all of the styles have the same vertical metrics. I submitted the issue in Glyphs Forum() and a fix was found.
It's because I need to add the "Export STAT table". But that tag is ignored and no STAT table is exported when using Fontmake int the GF repository. Is there somewhere I can change that in the config.yaml ?

Thanks,
Andreas
