Should Axis mapping Customer Parameters be saved in the font

Hi all

I have a variable font where I am using axis mapping to map the weights in the output font

This all works but I have noticed if I close and re open the font the custom parameter are no longer there

Is this correct or should the custom parameters be saved

It should be saved but if you have just a single variable font setting, you can add the Axis Mappings custom parameter in the Font tab.

Looks like it gets saved when added in the Font tab thank you
