I believe they are the False Positives and Malwarebytes says it is up to date. I was not trying to say that this was a separate event! Rather, that:
I received the 47 FPs
Quarantined and deleted them
Re-scanned; Malwarebytes came up clean
restarted my computer
re-scanned; Malwarebytes listed the 4 FPs I mentioned in my initial post.
