DynamicDNS Invalid Hostname Error with hostname in custom DNS

DynamicDNS, Add new a dynamicDNS rule selecting Custom on this page https://pfsense.domain/services_dyndns_edit.php and it throws a message sayinig invalid host.

Previous 2.1 customs worked just fine, and the migration to 2.2 still has the custom rules working fine ie updating the dynamic dns service until you attempt to edit and save.

In my example I just paste a specially formatted URL into the Update URL field, everything else is just default eg.

Service Type: Custom
Interface To Monitor: WAN
Interface To Send update from: Wan
Verbose Logging: unticked
CURL Options: All unticked
Username: left blank
Password: left blank
Update URL: My specially formatted URL complete with username and password and other options is entered here.
Result Match: left blank
Description: left blank

Error message is:
The Hostname contains invalid characters.

Update URL example:
https://www.mydnsservice.com/dynservice?username=7349509374cn7x4G&password=jhkkdsjfu77dfh3d3&hostname=www.mydomain.com&myip=%IP%&wildcard=%IP%&mx=%IP%&backmx=NOCHG
