Delete Vertex: Deleting Multiple Vertices - Connect U4

Good Day,

I have been having something new happen with Connect U4.

I have line strings that have been created many different ways with many vertices. As I go to delete a single vertex, the tool "delete vertex" will delete many of the vertices in the line string. It seems that it will delete about half. I have not seen this before in V8i through SS4. Is there a setting that I am missing for this tool?
