When an addon preset is created while no export format preset is assigned (value saved as None), and export format presets are later added to the addon, loading the original addon preset throws an error.
Root cause: The stored None value for the export format preset is no longer a valid choice in the updated enum, causing Blender to fail when trying to restore the property.
Fix: Added a fallback that safely handles a missing or invalid export format preset value when loading an addon preset.
