Hi,
When you say “duplicate” are you copying and pasting anything? This can cause problems with anim Blueprints. I see the issue occurring in the sample project, but am unable to reproduce it in any other anim Blueprint. I also set up a new anim Blueprint in the same project using the Tutorial TPP skeleton and tested it from there, and the transition rules still appears normally. I also am unable to get it to repro in a 3rd person project. It also appears that your skeleton is not actually there in the repro project and this may be contributing as well.
-Thank you
