Menu items not shown only from selected base item

ACCORDEON MENU CK 3.2.8 PRO

Thanks again for your help - and on a Saturday too!

I will check the problem by my side, don't hesitate to remind me next week if I don't come back to you

OK - thanks a lot! But until then I will remove the Joomla menu model from my site.... But as you can see on the attached screenshot, the submenu items of 'In Etappen' are not displayed in the Joomla menu module but are visible on the Accordeon menu module.
Have a nice weekend!

please try this version and tell me if it works
