Hi Jelsea, when you set NPC to false, certain NPCs still show up because they have a different type value. For instance, trainers, vendors, taskmasters...etc, all have different types. Also if you have ShowUnknown = true, then they will show up as unknowns.

I'm working on that
Maybe wyvern will correct me if I'm wrong, but Mob.Type is not really a unique value, but rather a set of flags that tells the game how to treat that object. So to make the radar more accurate I am currently mapping out the bit fields to see what each stands for.
Here is where I need help

I will post a version of radar with the option to show the type value for each Unknown node. Below is a list of the unknown types I have found so far, if you see any that aren't in the list please post them and I can make radar more type accurate.
Thanks
