Hi Eric. I don't think I can offer any help for this one, hopefully someone else can 8-)
If you know the exact Koha version you have (More > About Koha > Server information tab > Koha version), I could send you a list of the defaults for all the system preferences. Alternatively, if it is a relatively recent version, you could use one of the demos to identify what is missing https://koha-community.org/demo/ It would be a bit tedious though! (And might not resolve the cause of the issue.) Another thing to check in the database is the number of system preferences: select * from systempreferences; (for the current main there are 897 system preferences). Depending on badly your Koha is 'borked', another alternative may be to export your record data and import it into a fresh instance (depending on how much you have customised the frameworks and other administration options).
