VisibleDeprecationWarning when accessing tracks.fitinf and tracks.rec_stages

Whenever I try to access tracks.fitinf and tracks.rec_stages I get the following warning:

/pbs/home/z/zaly/private/km3flux/notebooks/venv/lib/python3.7/site-packages/awkward/array/base.py:394: VisibleDeprecationWarning: Creating an ndarray from ragged nested sequences (which is a list-or-tuple of lists-or-tuples-or ndarrays with different lengths or shapes) is deprecated. If you meant to do this, you must specify 'dtype=object' when creating the ndarray
  return cls.numpy.array(value, copy=False)

Not a big deal, but needs to be fixed ;)
