Enterprise - User specific credentials

Hi,
I created an "empty" credential with no username and password, only a name - its called "MyDomain1 Credentials".
I want users to edit the "user specific settings" for this entry to save their own login used for "MyDomain1".
This can be done by selecting the credential and clicking "Edit Credential Entry (User Specific Settings) Ctrl+Alt+U".
The user can then put in his or her specific username for the domain, and this one will be used when he/she opens sessions with the "MyDomain1 Credentials" set as credentials.
So far so good.
Problem is that the user specific settings on the credentials seems to disappear at different times.

One sure way to reproduce the following:
1. Create an "empty" credential
2. Enter username, domain and pw in the "Edit Credential Entry (User Specific Settings) Ctrl+Alt+U".
3. Right click the credential and choose "Edit Credential Entry (User Specific Settings) Ctrl+Alt+U" - verify that the username and pw is correct.
4. Right click the credential and choose "Edit Credential Entry... Ctrl+E"
5. Click cancel
6. Right click the credential and choose "Edit Credential Entry (User Specific Settings) Ctrl+Alt+U" - now the username, domain and pw is gone.
Please help resolve this issue or maybe give alternative solution to what I am trying to achieve.

Best regards
Nordberg
