You may set the proper submenu in the settings of every page via the Pages App:
As I may suggest you need to attach the appropriate menu to the sphynxlabs page and the other 5 pages too.
What is Inherit means?
Do i have to make a menu named Sphynxlabs submenu, because i did this but i can't see it.
Do i have to do here something?
Yes, certainly. You need to find your new menu there.
