Credential Repository set up

I'm trying to set up sessions using the credential repository feature. I set up a Folder to store UN/PW's as a credential. Then when I'm adding/editing a session (RDP, WEB, etc) I use, Embedded for Display, Credential Repository for Credentials and then select the correct option from the drop down that I've just added.

For the RDP session, I get a "Your Credentials did not Work" pop-up that allows me to manually enter UN/PW. This does not work either.
For the Web session, it opens up to the correct web page, but need to manually enter the UN/PW, but at least this does work correctly.


Am I forgetting something, or not doing the initial set up correctly?

Thank you!
