How to hide Affiliate links

Hello,

I installed WP Affiliate Manager and set up an affiliate program. The problem is that the link is written like www.mywebsite.com/?wpam_id=1.

I searched online and found a plugin said able to hide these links. I use the previous like as the target url and set up a new link like www.mywebsite.com/test123.

The link www.mywebsite.com/test123 is forwarding to the target url but the affiliate link is still visible.

I would like the forwarded link to appear like www.mywebsite.com/ and not with the ?wpam_id=1 at the end

Thank you in advance for the help
