I looked at this briefly:

I think the language codes for resources have changed to include multiple languages, but we're importing them as one. For example, https://findingaids.princeton.edu/catalog/C0022_c0145.json used to have a language of "English", but now it's "English French" - because it's actually two languages.

It looks like finding aids may even be indexing them as a single field:

{
"language_ssm": "English French"
}
