Department List of value in RUI are returning to many results, and advanced search are not available

Summary:

When using Responsive UI, the user are not able to select the required value for Department, when selecting from LoV. The search has returned many match, but not the one that are required. No more room in the list, I guess.

When using classical UI the department is very easy to add.

Content (required):

We want to create an Area of Responsibility, and we want to make use of the Department Hierarchy.

The name of the required department is "DTU Sustain".

When collecting the many matches, the LoV are not included "DTU Sustain, but a lot of other departments, meeting the criteria of the search. When navigating to the lowest section of the LoV, we expected to find an advanced search option, but none is visible.
