This happens because you have 'Development Officer' dimension on the Page shelf. By design, Tableau will display all elements of any other dimension on the sheet for each element of Page dimension (in your case - a person), even if there is no data for those combinations of elements. In other words, in your case, for each page (person) Tableau will show all titles in the data, not only those related to this person.
Try moving 'Development Officer' from Page to Filter shelf and see the difference. This would be a way to go, alternatively you can use parameters to achieve effect similar to Page scrolling, but without this side effect.
