Problem with a while inside a fork

Question

What I'm doing wrong?

This works well:

fork

  |System|

  repeat

    :Update location to User;

  repeat while (Approaching drop-off location?) is (not yet)

  :Notify to user "Driver is approaching";

fork again

  |Driver|

  repeat

    :Send current location;

  repeat while (On the way?)

end fork

But this causes a broken image instead of a diagram:

fork

  |System|

  repeat

    :Update location to User;

  repeat while (Approaching drop-off location?) is (not yet)

  :Notify to user "Driver is approaching";

fork again

  |Driver|

  while (On the way?)

    :Send current location;

  endwhile

end fork

Thanks for the report.
