After loading and matching a release, selecting the release/album row shows metadata correctly, but selecting an individual matched track leaves the metadata panel completely empty, no tag values and no visible column content.

After investigation, using user's original config file, it is caused by a missing script function (provided by a plugin).

A broken or plugin-dependent naming script should degrade gracefully: the informational filename preview may be unavailable, but the metadata box must still render the actual tag values.
