Property Manager System Options: Not able to delete the system options for an operating unit.

Hi,

Under Setup > System Options are listed one line per operating unit set up. To the right of these lines are delete buttons.

We only have one operating unit set up, and now we want to delete this setup but the delete-button is inactive and not working.

Have tried both responsibilities "Property Manager" and "Property Manager Super User" - but with same result.

The implementation guide does not seem to mention this button.

Do anyone out there know how to go about this?

Thanks and regards,
