Copying chosen glyphs from one master to another

I want to copy the outlines and metrics of some glyphs from one master to another (all in the same file), tried the paste special but actually does nothing… Am I missing something?
Thank you.

E.g. you want to copy the outlines in the Regular layer of A to the Bold layer of A?

This setting should do that.

And what version of Glyphs do you have?

Yes, it was this.
Thank you :slight_smile:
