While importing we are getting the following error

The export is taken from 8.1.5 import utility. In 8.1.5 if we have a primary key on a column and if we try to create a unique constraint on the same column Oracle will give an error. If that is the case then how the above two statements came into the dump file while is creating an error while importing.
