Just out of curiosity, you are sure that your "%hostname%" data element is being properly set?
You should be able to test this on the front end of your site by opening up the browser console, and running the following script:
_satellite.getVar('hostname');
If you aren't familiar with using the console, you can type JS code next to the blue chevron and hit enter to execute:

If "Hostname" is set, the value should appear underneath, if not, it might come back as nothing or undefined.

I just want to be sure first off that this subdomain and ECID opt-in is properly configured. It's probably okay, but it doesn't hurt to check
Update: I should note that Data Elements are case sensitive (hostname is different from HostName or Hostname or hostName < different variations of case formatting)
