Can you tell us how the phylogenetic tree was created? Are you using a reference genome and the aligning all strains to it?
It was aligned to a random genome in the list. Using the "-r !"Parsnp command
What program are you using for this? In the past I have always worked with individual genes when creating phylogenies.
Raxml. this is core genome alignment
What do you mean by "core genome alignment"? An old post on biostars questions ability of raxml to do whole genome phylogenies: Phylogenetic Analysis Of Whole Genomes Perhaps someone else may have additional suggestions.
The possibility of samples being mislabeled (during submission or prior) is there.
You may find this paper interesting.
One would hope things have progressed in 5 years since that post!
I would recommend spending some time formatting your question so that it is easier to read.
