Incorrect results reporting In module projectestac/Rgrade within moodle with marsupial

[olmanton]

When an activity result is returned to the moodle via Marsupial with the status INCOMPLETO
e.g
ns1:EstadoINCOMPLETO</ns1:Estado>

The Activity score (calificacion) shows with a NaN error in the Rgrade Book summary page for the reporting user.
the larger info box for the activity does show the correct score, but the overview is inoperative becuase of the NaN
error.

The Standard Marsupial view in "GRADES" is not viable because of the need to create an access button for every single activity per book (perhaps 1000's) before scores register in the grades module.
scores sent before creation of the button do not show in the grades module.

5+ attempts were made at the activity in question.
If the activity status for the attempt is changed in the moodle database, Rgrade reports the % score correctly
in the summary view as well as in the detailed view.
If a tranlastion of this text in to Castellano or Catalan will help please let me know.
Also I can provide full logs for all the marsupial SOAP messages involved.

Thanks,
Oliver

Versions: in the test documented above:
Moodle 2.8.5 20150310
Marsupial 201412400
Rgrade 201609500 (upgraded from 201412400) no change in behaviour

Note
Moodle 3.7 with the latest master branch builds (not the realease versions)
of Marsupial and Rgrade displays exactly the same problem.
