Taxonomy: Snodgrassella classification not consistent

Hello,
I have noticed an inconsistency in _Snodgrassella_ classification in the database. In some cases, this genus is classified in phylum Pseudomonadota (which I believe is correct, based on other sources) and in some cases - in phylum Proteobacteria. The remaining taxonomic ranks, below phylum are identical. How should I interpret this entry?
Thanks,
Weronika
