Can't remove IP?!?!? What the ..

Hi,

I am using SQL2014 with HA/AG groups and was adding an extra listener when I used the incorrect IP address. 

I had thought the 'remove' button would work, but it does not. Also I tried deleting it manually:

[quote]
delete from sys.availability_group_listener_ip_addresses where listener_id = '26d37cdb-5a6f-43a0-ab0c-f4343eeac0f2' 

delete from sys.availability_group_listeners where group_id = '6B060505-CDDC-44B6-A9AD-38FC6AD4A7AA'[/quote]

Ad hoc updates to system catalogs are not allowed.

I attached an image.

How can I remove the invalid IP?
