[keycloak-user] Why is the Base URL repeated in client configuration?

Hello, I am configuring a client in the KeyCloak admin console, but am having a trouble to create an client to secure. Specifically, The Base URL field is wrong (repeated), as I saved in the configuration page. Please see the two attachments for an illustration of the the issue. This looks very weird. As you can see clearly from keycloak2.png, the base URL i typed is repeated, thus invalid. Thanks for any information that might be helpful. Martin
