How edit a question defined as Identifier

Hello Survey Solutions team.

When I was loading a packet of assignments I done a mistake and I wrote a wrong value in one of the question defined as Identifier.
Now I can’t edit this wrong value with any role of users (HQ, Supervisor or Interviewer).

What I can do in this case?

Thanks for support me.

Archive the incorrect assignment. Create a correct one either manually or through the upload of a file.

Thanks @sergiy for your help.
