Why did Edifix link, but not correct, my “No Format” references?

The No Format option is specifically designed to preserve your references exactly as they were submitted. If you select PubMed and/or Crossref Correction and Linking, Edifix will attempt to link your parsed references to PubMed and/or Crossref and retrieve PMIDs or DOIs, but it will not make any other changes to your references.
