Do you have other events that change the boss speed or set the run animation? With just those events shown it should technically work.
A way to completely avoid trying to play both animations at the same time is to add a condition to the 'is moving' event which is 'tired animation is not playing' so it will only play run when tired is not playing.
However it would be good in this case to find out why it's still playing run anim when speed is 0, so that's why I asked about other events.
