The “X section” is not accessible from the main section
A very frequent error is leaving sections without a link. A section like this is not accessible from any point of the application, which means, from no section.
As it’s shown, the “locate” section is not accessible from any point.

To solve this problem, on one of the created sections, the “locate” section must be set as destination .
In your case, you must look for the no linked section. Then access it and set it as any option destination.
