All masters have the same number and order of TTF stems defined.
It doesn’t show masters. It shows the current instance from the preview. Have you tried changing the preview instance?
What do you have selected in the preview popup?
I have the default option selected, but it shows the same for all options.
I have fixed a small problem with the updating of the instances. It might fix this.
Yes, there was indeed a bug where the instance got stuck after certain edits. Thanks for reporting Look forward to 2.3.1.
When no instance is selected, the preview panel shows the currently active master. Seeing as TTF stems are tied to masters, couldn’t also the hinted outline do this?
