Connect doesn't display Fitcontributions

Finally I implemented two fit contributions in my app and the fit file generated looks good in the Monkeygraph tool.
I created two fields with the mesgType=>Fit.MESG_TYPE_RECORD attribute and all the stuff in the resources file,so the file generated is properly shown in the Monkeygaph;I tried both with the one made by the simulator and both with the one made the Fenix 3...same result....Garmin Connect apparently ignore the fact that there are some fit contributions and doesn't show the graphs....I really don't understand why and every help is well accepted.
Thank you in advance.
