2 of my pages I can see in reality - but I can not find them in my path list “Baumansicht”. Where could they be?
Please provide more details, if you want someone to be able to help you. And what do you mean with “Baumansicht”? The page tree in the backend?
As you can see the two page trees are different - and I do not know how i can find the missing pages??? www.dellefant.de
You backend screenshot suggest that you are a limited user.
The page you can’t see in your backend pagetree (but is visible in the frontend) might have a different owner than what you access groups gives you access to.
Contact a admin user of your installation - they can look into that 
Thank you so much!!
have a nice Day
