For some reason after completing a second node sync from that page, I was then able to remove the node from NCM via the NCM manage nodes page. I see it's completely gone from the NCM on the server as well. I've also now removed it from NPM, so it's completely deleted from both databases.
Now that everything is cleaned up, I try to add the node back in, but it is only showing ports 23-50. I'm baffled as to why this is happening.
