Yeah, tags here are a bit confusing. You request tags you'd like to have and generate tries to build a dungeon satisfying those tags, but it often fails to get exactly what you were asking for. It was the first generator with this tags interface and I didn't know what I was doing :) I'll have to remake it one day.
I'm not sure I get what is the problem with notes, but changing their mode (Notes in the context menu) to Default, Tailed or Legend will probably help.
