Not showing users on "Add Grant" option

Question

First of all, sorry for my pour english.
I'm trying to do some exercices with EM Cloud Control 12c. One is:
b. Specify who can share, edit or even delete this shared credential using one of the three
privileges (Full, Edit, View).
• SYS user with Full privilege will be able to use, edit and delete the credential.
• SYSTEM user with Edit privilege will be able to use and edit the credential.
1) Click “Add Grant” then select the user SYS to be added in the Access Control list.
2) Repeat this operation to add the user SYSTEM.
By default, the selected users are granted the View privilege only.
3) To grant Full privilege to SYS, select the SYS user and click “Change Privilege”.
Choose Full and click OK.
4) To grant Edit privilege to SYSTEM, select the SYSTEM user and click “Change
Privilege”. Choose Edit and click OK.
3. Test against the orcl database instance, click Test and Save until you get the following
message: Confirmation Credential Operation Successful. This means that the credential
was successful and saved.
When I try to add grant I can't see the users, like this:

Can someone help me with this?
Thanks in advance.

Hi CourtneyLlamas. Thanks for your reply and again sorry for my english!
I'm trying to do some exercices from Oracle Database 12c: New Features for Administrators (D77758GC10) traininig, and the exercice says:
'Practice 1-3: Creating New Named Credentials
Overview
In this practice, you create the credorcl credential used for any connection as SYS user
sharable in the database instance orcl.
Assumptions
You completed the practice 1-2 to add the orcl database instance as a new target monitored
by Enterprise Manager Cloud Control.
Tasks
1. Navigate to Setup > Security > Named Credentials.
2. Click Create.
a. Enter the following values, then complete the Access Control section:
Field Choice or Value
General Properties
Credential Name credorcl
Credential description Credentials for Database
Authenticating Target Type Database Instance
Credential type Database Credentials
Scope Target
Target type Database Instance
Target Name orcl (Click the magnifying glass
to find orcl and select)
Credential Properties
Username SYS
Password oracle_4U
Confirm Password oracle_4U
Role SYSDBA
b. Specify who can share, edit or even delete this shared credential using one of the three
privileges (Full, Edit, View).
• SYS user with Full privilege will be able to use, edit and delete the credential.
• SYSTEM user with Edit privilege will be able to use and edit the credential.
1) Click “Add Grant” then select the user SYS to be added in the Access Control list.
2) Repeat this operation to add the user SYSTEM.
By default, the selected users are granted the View privilege only.
3) To grant Full privilege to SYS, select the SYS user and click “Change Privilege”.
Choose Full and click OK'
4) To grant Edit privilege to SYSTEM, select the SYSTEM user and click “Change
Privilege”. Choose Edit and click OK.
3. Test against the orcl database instance, click Test and Save until you get the following
message: Confirmation Credential Operation Successful. This means that the credential
was successful and saved.'
I'm logged with SYSMAN account, like the exercice asks, and I'm trying to Add Grant to user SYS. The exercice is wrong? Am I doing something wrong?
Thanks in advance.
