can't change loop time

If you see closely in the inspector pane I can’t change any settings from the animation in the inspector pane. How can I made those settings active and finally change the settings like the loop time?

press on the parent of the animation and from there you will see 4 options in the top of the inspector saying model rig animation materials go to rig and rig the character either with the avatar you have or another avatar and then go to animation and everything should be there
