OffsetCurveGenerator generate gaps within one of the offset multiCurve output lines

Hi guys,

I've seen that the transformer "OffsetCurveGenerator" creates me some gaps on one of the offset lines generated.

Here are the parameters set:

The input line from a ESRI Shapefile, which makes the issue (nothing really complex..):

and here is the one on which has been created gaps (PINK) right side, and (BLUE) the Left side with no gaps:

As you see, the other MultiCurve line, well created is the LEFT side from the transformer output. But the RIGHT side (pink) is created with gaps.

I need to say that I tried to isolate that line, and the output stays the same.

I use FME Desktop 2015.1.0.1 - WIN64 - Build 15480.

Thanks for the help,
