Reseed Identity Column but the change is not reflecting in Identity Specification (Table Design view)

I have an identity column with configuration (emp_id int identity (10,1). It is understood that when we truncate the table the identity start from its specified values .Means start from 10 again. But when I truncate the table reseed the identity column DBCC CHECKIDENT ('employee',reseed,1). It will start putting the values 1 in the identity column. But the reseed change which is now 1 instead of 10 will not updated in identity specification (Design view of Table) section. It is showing the same old value (10) which we specified at the creation of the table.
