Unable to save actions to Favorite folder

I'm on KM version 10.0.2. I am unable to save actions to the Favorites folder. I can add the actions in the editor, but when I quit the engine and re-launch it, the Favorites folder is empty. Any suggestions?

Thanks!

Is this how you're saving Favourites?

Yes, as well as by dragging actions into the Favorites folder. They appear in Favorites as expected during the current session, but disappear after quitting and relaunching the KM engine.

Oh that is weird. Hmm. Maybe one for @peternlewis?

Favorites are saved in the macro file - are other macro changes being saved?

Update: I just upgraded from v9 to v10 - the problem has resolved. Thanks!
