I check and the issue comes from Plazi DwC-A, so maybe is an export problem as I don't see it reflected on the Plazi website. Neither I could find a reference to a synonym inside the treatments

This dataset is also missing the authorship + year

The article has some citations of undefined species

It seems that all these you listed are such cases.

I see, but even in that case is not a good practice to add "sp." or "undefined" on the dwc:scientificName, you could use dwc: verbatimIdentification and/or dwc:verbatimTaxonRank
