allow vpn client export of other to be a blank field
Under: OpenVPN -> Client Export -> Host Name Resolution -> Other
The Host Name field that appears requires a value to export the config.
What if you want to define your hostnames under advanced? It seems a value of blank would be a valid value for "Other".
To work around this right now you can select Hostname DDNS Multiwan as a value for Host Name Resolution and get a value as blank.
It seems though a more correct solution would be to select Other and leave the field blank.
