Extr.2 isn't working properly. g-code is different to Extr.1

With the new Version 4.0 I can't use the second Extruder.
Printing with Extruder 2 is extremely slow.
The g-code of Extr.2 are different to Extr.1

For example g-code of S3D 4.0:
Extr.1: G1 X129.684 Y115.610 E0.0041 F2520
Extr.2: G1 X129.684 Y115.610 Einf F2520

S3D 3.1.1:
Extr.1: G1 X129.684 Y115.610 E0.0059 F2520
Extr.2: G1 X129.684 Y115.610 E0.0059 F2520

What does "Einf" mean?
Correct me if I'm wrong, but it should not be there, I guess.

The support of S3D send me a new FFF-Profile.
Obviously I messed it up, a little bit.

Great job!
Thank you!
