  I can't reproduce your issue on my end, but I can offer an alternative method. Another way to create the circle example you've provided is to use a *Radial Wipe effect* on the shape layer:
  
  ```
  Effect > Transition > Radial Wipe
  
  ```
  
  Just animate transition completion from 0 to 100 percent. If your shape layer is moving, you may also need to pickwhip expression the *Wipe Center* parameter to your position parameter:
  
  ```
  transform.position
  
  ```
  
  I hope this helps you out. Good luck!
