Issue — When you open an account, the Account Identification Overview Page shows all Contact Persons belonging to the account. Contact person is shown as TITLE, FIRSTNAME, LASTNAME. When you sort contact persons, it includes sort results to include the Title (ie: Mr, Ms, Prof, Dr. Adm.etc). For example, if you select Sort by Ascending in Contact Person column and Contact person title starts with letter ‘A’ eg. Adm., that contact person will show first in the list regardless of his first name.
