Export Generated URL

HI, i have installed SuiteCRM 7.7.9, the issue is when i create a new field in leads module, they should generate URL like domain.net/{id}
and he does. But on export the leads i expect something like domain.net/sdfsd9800ovaf90, but i get domain.net/{id}, what do i wrong?
why on export i recieve id placeholder and not value of id?
