It is spelled indentifications.csv rather than identifications.csv
Reported By: Duke and Symbiota themselves
Note that there is a minor error associated with the Specify dwca.zip output file, which DUKE previously brought up as a possible reason for the issue. The identification file is named indentification.csv (extra n). However, it’s not a problem because the misspelling is included correctly within the meta.xml file.
