The “X” section has no type signed
When you create sections with Mobincube, these are shown with an icon with an exclamation mark “!”. This means that they don’t have signed a type of section, so we didn’t tell Mobincube that this section will be a menu, a map, an information section, etc.
As you can see, the “locate” section icon has an exclamation mark. However, the other sections have their own representative icon.

To solve it, you must find the “X” section on the section tree and by double clicking on it you can sign it a type.
