Page is a not externally linkable

The "Type" field you are seeing is sent by the server - in the HTTP header that precedes the actual HTML file. So that information is not coming from the <head> section of your page's HTML or from its meta tags.
The server itself is set up this way (in error, IMO) and that is where the change needs to happen.
