are you hitting the save button at the bottom? i am running the newest version of osx as well. if i hit save then shut down creator and restart it then hit the add button to make a process come up it will bring the same process and setting up i left off with. i dont ever have to import anything unless i want to completely change to a different custom profile.
so when your process window is empty after restart and you hit the add button and the process pops up what exactly is the process it gives you? its not the one you left off with? is it just one of the defaults?
