This means that the animation option in your game is turned off.

Open the game's settings (the round yellow cog button at the bottom of your screen), then you’ll see a button with a picture of a person. You can turn the animation on and off by clicking on it. It will be Yellow as shown in the picture when it is turned on.

If your quality is set to low then it wont turn on so you will first need to raise the quality of the game and then you will be able to turn on the animations
