The model's type field is an IntegerField yet the actual values in the
choice tuples are strings. This works OK for storing but fails to match when
the real value retrieved from the DB is an integer, since '1' == 1 evaluates
to False, for example. Thus get_type_display() doesn't find any choice that
matches the retrieved value and falls back to returning the actual value.
Switch the '0', '1', '2' in TYPE_CHOICES to 0,1,2, and it will work.
