Added Island don't load in the editor

Created a few islands (Add Island method) - Created name, x,y size, override index -1, added sublevels and extra sublevels - saved the project, exported it. Closed the application, next day I open the ServerGridEditor, loaded the project, and notice all the added islands I created aren't listed anymore, and no longer show up in the grids.

Not saved, or doesn't load the "Add Island" (Added Islands) from the json file, so loading the project doesn't display the added islands.

After digging around, I notice an islands.json file in IslandExtensions folder, if has the custom Added Islands I created. To make them load up with the editor, I went to Data and edited the islands.json file there, at the bottom I added them. Now when I load my project, the islands are there.
