Clicking on series or subseries in Collection contents gives an error

In a finding aid with series (example: https://sclfind-arclight-staging.galib.uga.edu/catalog/RBRL-148-MFM), in the left navigation "Collection contents", you get a generic error message when you click on the series. This also happens with subseries (e.g. A. Office Procedures under Series II).

It should be going to the page for that series or subseries. Clicking on any other level in Collection contents, including the top level when it is not a series (example: https://sclfind-arclight-staging.galib.uga.edu/catalog/ms4324), works as expected.
