Lookahead feature doesn't come back.

Hi, in 2D project I have CinemachineVirtualCamera with lookaheadTime set to non-zero value. When camera's target is moving, then everything is fine, lookahead is doing its job correctly, yellow square (in Game Window Guides) that indicates offset target is positioned before the camera's target. But when camera's target stops, then offset target doesn't fully come back and eventually isn't positioned perfectly on camera's target - in result, despite dead zones being set to 0, camera's target isn't centered by camera. Is there any way to fix this or do I need to write my own scipt, that sets lookaheadTime to zero when camera's target stops?
Thanks in advance.
