The difference there is all in the folder format (columns etc.), so you've probably got Preferences / Launching Opus / Default Lister / Ignore folder format of Default Lister, and your default folder format isn't the same as the format you've saved in your "Standaard" layout.
If you want that folder format to be used everywhere by default, I'd leave the option on and follow the guide to make your desired format the default. Otherwise the format will start changing when you go into different types of folders, even if you get it how you want when the windows first open.
