In the Lexham Hebrew Bible (LHB), if you double-click on the word for "leprosy" [tzara'at] it takes you to TWOT, DBL Hebrew, or BDB word 1898B [mesura] "stronghold." The Biblica Hebraica Stuttgartensia goes to the word for leprosy in the dictionaries. The problem seems to be with coding in the LHB, not the dictionaries.
This has also been reported as a typo.
