Repository: "Edit metadata" shows all licenses, not licenses selected for repository

Describe the bug
As a Repository Manager, I am sometimes asked by the submitting author to update a preprint's CC license because they are unable to do so themselves in the Metadata Correction/Update workflow. When I use the "Edit metadata" function to update licenses, however, the system displays all licenses in Janeway, and not only the licenses that have been selected for use in the Repository. As I do not have access to view all the licenses available in the Press or select the licenses in the Repository Wizard setup, this can be especially confusing for me.

Janeway version
Seen in 1.5.x and 1.b7.4.

To Reproduce
Steps to reproduce the behavior:

1. In a Janeway Press with many different licenses, log in on a SuperUser/Admin account and confirm the selected licenses for the Repository:
   

2. Log out and log back in on a Repository Manager account, then start a new submission; confirm that only the selected licenses are visible to a submitting author:
   

3. Go to Repository Manager and select a published preprint, click "Edit metadata", then try to edit the license; note that all licenses in Press are visible:
   

Expected behavior
Only a SuperUser/Admin account would see all licenses in Janeway in the "Edit Metadata" functionality. Repository Managers should not see the other licenses available unless they are updating a preprint which has a license that is not currently supported (i.e. they would see that unsupported license, then only the other supported/selected licenses).

Reproduce the Repository Manager workflow described in the issue, starting with Repository Manager and the “Edit metadata” function. Trace how the license choices are assembled and compare them with the licenses selected in the Repository setup. Done means Repository Managers see only supported selected licenses, plus any license already assigned to the preprint, while SuperUser/Admin users still see all licenses.
