Exporting Max For Live Devices, Save as Project disabled

Rasael's icon

I am having trouble sharing devices I create on M4L.

Somehow I managed to workout with one using the following flow:
1) Open the device in M4L
2) Press "Save as Project" in the File menu
3) Press "Show containing project"
4) Succesfully export device

So now I can share that particular device. Problem is that on my other devices I dont have the Save as Project option.. Why is that?
Also if I open the show containing project without saving as project the export option is disabled, why so?
