How to fix this error?

The dependency affects the selection of dependent entries in the
navigation. The following values can be specified:
H : Header entry; the object has no predecessor, it's own name is
specified under predecessor.
S : Only ONE entry can be marked in higher-level object in the object
navigation. Dependent entries are thus always only displayed or
maintained for ONE higher-level entry.
M : SEVERAL entries can be marked in the higher-level object in the
object navigation. The dependent entries for all marked higher-level
entries can be displayed or maintained together in the current level.
