The NBEditor can get a bit buggy at times. Try hitting the refresh button there at the bottom of your JBeam file on the left. That resets the view window to be up to date with what is actually written in the file.
Ok, so if that doesn't help, that means that those nodes are getting duplicated somewhere in your JBeam file. Unlike normal JBeams where everything must be listed in a very specific way to get them to work, the Editor just recognizes the pattern of numbers and figures out if its a node or a beam... no matter where it is in the code. So... in your JBeam that you have there, do you happen to have more than 1 part in that file? Perhaps several different versions of the same hood? If so, the editor may be pulling the nodes from a different hood lower down in the file. For whatever reason, even if you highlight all the nodes in the file on the view window and move them, only the nodes in the JBeam at the very top of the file will actually be edited. So when you save, everything else in the file except the nodes in the very first JBeam will go back to where they were in their un edited state. This is one of the biggest drawbacks to the Editor in my opinion. It is almost (not entirely) impossible to work on JBeam files with multiple JBeam parts in them as the editor has no way (that I am aware of) of filtering which JBeam to display and apply changes to. The way I have gotten around this quirk in the past was pretty simple. I would first make a copy of the file that I wanted to work in. Then, I would open that copy and delete all the JBeams inside of the file OTHER than the one I actually wanted to work on. Then I would open that copied file in the Editor, do the work, and finally save the file. Finally I would open the copied file in a text editor, copy its contense, and then paste it into the original file replacing the old JBeam that I was working on in that file. If this is not the issue and there is only one single JBeam in that file, then scroll down through the list on the left of your screen. Somewhere in that file the program has duplicated your nodes and you will probably find them stuffed somewhere random in the file, and the editor is displaying them regardless. If you delete those copys, then all should be well with the world again.
Right, so to work on them, you need to separate the JBeams in the files into their own individual files first. Then you can open them up in the Editor to work on them.
