Problem with Workflow to create booklets on Konica 3070 with IC417 rip ver2

[rapsport]

Does anyone know how to solve this problem?

Machine (konica C3070) IC417 Rip with ver 2 software

Problem when creating a booklet workflow which has a different media for the cover.

Created imposition in impose and ticked cover, but only selected both sides option. Saved as a preset in impose. Opened preferences for job selected media from paper catalogue (100gsm) Then went to layout and selected impose and my preset template. Then edit and selected cover where i then selected the media (200gsm) from my paper catalogue.

Went back to media. Mixed media settings showed the cover stock.....All is well. I then selected relevant finishing options and saved the whole thing as a server preset so I can access as a workflow.
The job prints correctly the first time I use the workflow, but if I select a different quantity it doesn't print correctly and loses the cover settings.

It will randomly staple two booklets together, output as a flat sheet or skip the cover.
This only happens on booklets with a cover. SD-506 finisher on a C-2070
