XL Deploy plugin not listing the credentials

[Ranjith Kumar]

I am trying to use XL deploy plugin to deploy my project to a remote server in AWS. I have added my .pem file with secret file option in credentials, but the newly added credentials is not listed in the Manage Jenkins --> Configure System --> XL Deploy Plugin. Please find the screenshots below.

If this is a bug, let me know for any other alternatives.

Thanks,

Ranjith
