Missing opening track - what mean, how do?

[AnyNameYouWish]

Hey all, I'm trying to salvage and make something out of the alien queen portrait model in this bundle. As only has a stand animation, I broke up the stand animation into birth, stand and death, making sure that none of them start or end on the same frame as another. I put it in the sanity tester and got some severe warnings about things called 'missing opening track' at bones. I'm very lost. It also says that the animations are out of order but I made it so the frames are in order? Why can I not manually reorder the animations? Sorry if I'm not explaining this well, I'm new to a lot of this. I've attached the model and screenshots of the errors.
