Fresh Odoo 11 Installation with the awesome install script by Yenthe! (Thanks a million times)

If you select Germany as country, SKR03 and SKR04 are being installed. However if I want to change from SKR03 to SKR04 it throws an error and I cannot change it. We need this for accounting.

Please help.
