I have also seen the error. But I know from Elli Stammer and Irmgard Belanger that she is Augusta. I think it can be an error by the duplicate-process from the church book. Some of the original church books are still in the church. My father visit the church in Zvyriai and look into original church books and not duplicates.
In the church book on Familysearch is Augusta!. The entry on Site 159 is russian! I think a translation-error from your source of the church book record.
