Occurrences problem

The number of sequences pulled out from PhylogatR and number of samples in occurrences files does not match, for example, Aurelia aureta has 153 sequences but only has 5 samples in occurrences file.

The sequences also have 2 different pattern: >KP728367_2307989198 and >00000000_CNIDC132-15. One is GenBank accession number and another is BOLD?
