^I have an issue like this that happens quite often; I don't know why but it's super annoying. That being said, all it takes for me is to highlight one of the notes, and then use the arrow keys to move the pitch up and back down again (or down and back up) by even just a single note. Moving it around makes finale respace everything in the measure, so I only really have to do this once per measure, regardless of how many problem notes are involved. Again, though, I have no idea if that's a possible fix on Notepad...
