21.5 WAF + Wildcard | Cannot remove *.domain when creating WAF Rule

Hi guys and gals!

As stated in the title, I noticed with the current version there seems to be a bug when creating a WAF rule. I have a wildcard certificate installed on the appliance and just wanted to make a new WAF rule, but noticed when I select the SSL certificate the two placeholder domains (domain.com and *.domain.com) show up in the DOMAINS box. This is not new, but now I cannot remove these two entries and replace it with what I want (example.domain.com). 

I can add the EXAMPLE.DOMAIN.COM, but the two other entries remain and I cannot edit or remove them. This would defeat the purpose of the WAF function since I want to route specific subdomains to different servers.

Am I missing something or is this an actual bug?

Cheers!
