Issue in Transportation

I create a Volume Shape1(blue) in the Envelop (white,Box) and specify an e- .
I see the particle always in Shape1, but the print result display that the particle in Envelop.
What should I do?

I set StepLimiter in Shape 1. You can see the yellow point in the red line that mean it working.
And you also can see the red line without yellow point which meaning the Particle isn’t in Shape1.
Actually it shuold be in.
Shape1 is showed.

    G4Ellipsoid* solidShape1_3 = new G4Ellipsoid("Shape1_3",shape1_sizexy/2,shape1_sizexy/2,shape1_sizez,0,144.5*mm);
    G4Tubs* solidShape1_4 = new G4Tubs("Shape1_4",0,160/2*mm,10*mm,0,2*CLHEP::pi);
    G4MultiUnion* solidShape1 = new G4MultiUnion("Shape1");
    G4RotationMatrix rotm  = G4RotationMatrix();
    G4ThreeVector position3 = G4ThreeVector(0*mm, 0*mm, 75*mm);
    G4ThreeVector position4 = G4ThreeVector(0*mm, 0*mm, (75+144.5+10)*mm);
    G4Transform3D tr3 = G4Transform3D(rotm,position3);
    G4Transform3D tr4 = G4Transform3D(rotm,position4);
    solidShape1->AddNode(*solidShape1_3,tr3);
    solidShape1->AddNode(*solidShape1_4,tr4);
    solidShape1->Voxelize();
