pfSense

Hello. I am on pfSense CE 2.6.0 and when I try to create or update a client record for the dynamic dns provider "name.com", i cannot input a blank host. Whhen I tryto use a blank '' or '@@' the hostname, it is not saveable and the red 'error' banner is displayed and the error is "The hostname contains invalid characters". However, this shuould be is valid as per https://www.name.com/api-docs/dns#CreateRecord (same information listed for UpdateRecord)

host (string)
Host is the hostname relative to the zone: e.g. for a record for blog.example.org, domain would be "example.org" and host would be "blog". An apex record would be specified by either an empty host "" or "@".
