Multi-laying on CAM

Hello, I do machining on DMG Mory (CMX50U = 5 positioned axes) and I have SCHUNK equipment for the installation of my parts.
I want to do the CAM of 2 separate parts with for each a 3-axis milling phase and a turning to finish the part.
I have at my disposal: Zero Point, Pyramid and SCHUNK Vice. of which I made an assembly called: multi posage,
I have created copies of my 2 parts to configure them in their respective machining phases and I put them in position as they are in the machine.
I declared the 4 pieces in the CAM shape tree,
I have associated for each piece the rough that corresponds to it.
All this is OK.
The creation of the different tools: OK
When I create my toolpaths:
Part 1 = OK (all machining is done well)
I add Part 2 (same part as part 1 but turned over) = OK (all machining is done well with 90° rotation of the table)
Part 3 (new part) = Ok / not OK (machining on part 2 is done well but I lose tool paths in part 1 on the 2 placements) => ???
what happened for SolidWorks CAM to decide to remove machining...
In addition, it generates shapes and configurations for me without necessity.
I admit to being perplexed. The different origins are consistent with reality.
I don't know how to attach the complete folder (37 MB) so that you have the files to see what I did (for good or bad).
Thank you in advance for your answers.
