OJS 3 Automatically generated in email templates is dead

Hi,

We just recently upgraded from OJS 2 to OJS 3. I am not sure of the version number. Can anyone tell me why all of the automatically generated content in the email templates are dead? I just see place holders and the system does not automatically fill in the information. Most importantly, the peer reviewer link that was formally there is no longer there. Can someone tell me how what to do in order to ensure that the automatically generated content in the email templates shows up again?

Thanks.
