Safety Height Reverting to 3.8mm

Hey all, is this a feature or a bug hehe?
New projects are always set to 3.8mm despite me setting this differently in the previous project:
I set it to my preferred value (Machine>General Settings>Safety Height), I even tried saving the project as default.

I may be misremembering but I thought this value used to persist once set?

Thanks :slight_smile:
