Before we jump into SQL queries to try resolving this (which can get complicated, since the information in an authority record is spread across several tables, as I understand), have you tried reindexing your site? It's possible the record is just an artifact in the search index, which is why you can't click on it. See:
You may also want to try regenerating the slugs. If the record has no slug, then this could prevent you from clicking on it as well.
If neither of those tasks work, I will see if one of our developers has further suggestions for you. In the meantime, can you provide us with more information about your installation environment? I recall from other threads that you are working with AtoM 2.4... did you install using Ubuntu and Nginx as as we recommend in our installation instructions? If so, which version of PHP and Ubuntu are you using? If not, what changes have you made?
