Hello, We're working on upgrading our instance of Koha from 3.6.4 to 3.14.7, and we've run into an issue with the UseAuthoritiesForTracings setting. It doesn't appear that Koha is obeying this setting, as we're seeing some subjects link to "an:###" searches instead of "su:Words" searches. The tricky part is that it's only some records, not all. It appears to be on a bib by bib basis. We're not actually using authorities at this point, but at some point in the past some authorities records were created. Is there something we're missing, or something we should be deleting to correct this?
