Shortcode not working

Hello,

I’m have attempted to use all of the following shortcodes:

[referrer_user direct=”true” display=”user_nickname”]
[referrer_user direct=”true” display=”user_email”]
[referrer_user direct=”true” display=”user_url”]
[referrer_user direct=”true” display=”display_namel”]

All outputs result in displaying nothing other than the referring affiliates username.

Please help me figure this issue out.

Thank you!
