I don't know if the mistake is in the CAM setup or decal building but I don't see past mask into CAM preview.
In attachment CAM setupo and PCB File with the component.
The original decal is download from supplier.
First you need to check if your decal pins include a paste layer for the top. If it is included be sure when you generate the gerber for the paste mask to include the paste mask layer and that the PAD for the paste layer is selected.
If your decal pins do not include the paste layer for the top, When you generate the gerber for the paste mask top you must include the top layer and the PAD fot the top layer must be selected.
