Untraced references showing as valid subject headings
Authority records with 008/09 of "b" shouldn't be showing as authorized headings. These are untraced references not authorized headings. (I found this on the record with LCCN sh 85038380)
Form https://www.loc.gov/marc/authority/ad008.html :
b - Untraced reference
100-15X field contains an unestablished heading that is not authorized for use as the element in an access point in a bibliographic record. The heading is not traced as a 4XX See From Tracing field in any other authority record. The reference record contains a Complex See Reference (260) or a General Explanatory Reference (666) field to guide the user to established heading(s).

This error is also occurring when 008/09 is "c" (traced reference). My suggestion is the same: do not show unauthorized headings as authorized. The authority record is LCCN sh 85077662.
From the same website as my previous comment:
c - Traced reference
100-15X field contains an unestablished heading that is not authorized for use as the lead element in an access point in a bibliographic record. The heading is traced as a 4XX See From Tracing field in one or more other authority records. The reference record contains a Complex See Reference (260 or 664) field to guide the user to established heading(s).
