Export and Import looses credentials

I am trying to export from my old laptop to my new laptop, however on import, none of the credentials are linked, I can't edit the parent folder to use specific credentials, it's like none of the options are there.  I mam on version 2018.

---EDIT---
I have fixed this issue by doing the following:
"So please right click on the Connection-tree root, select Folder Properties and check the "roles" setting: "Credentials" should be activated"

That solved my problem.
