The Catalogue of Life uses information from very different sources. The classification for a given taxa depends on the source. For example, the information about this Phylum: https://www.catalogueoflife.org/data/taxon/9JHQ8 comes from the Bryonames: Bryophyte Nomenclator (see the source dataset at the bottom of the CoL page).
In doubt, I suggest to check the source for a given taxon.
