Overcategorization

A sought resource is classified under an unnecessary organization scheme.
Hierarchy chart. 1, 2 and 3 are hierarchically under "...". C is repeated under 1, 2 and 3.
The organization scheme formed by 1, 2 and 3 is unnecessary to get to C.
Example

In some countries it's a common practice, and sometimes expected by users, to ask for the preferred formal titles on forms, such as Ms, Mr and Mx, for women, men and non-binary persons.

Sometimes Ms is replaced by two options: Mrs and Miss, two formal titles indicating married and unmarried women, respectively.

Providing only these two title options to women creates an implicit organizational scheme that forces them to disclose their marital status in order to access desired resources, becoming overcategorized.
