Why do I lose all my digger Images on my views when I Save and close my Composer?

Hi Guys.
My problem is as follows.
I am working on a rather large project at the moment. And normally I do not turn off my computer at night and I leave my composer running
So I can just walk in the next day and carry on.
Now in this project I  have over 150+ Images and 80% of those Images have diggers to show detail.

But each time I save my composer document and shut down it somehow deletes the 2D digger file.

And once I reopen composer there are no more diggers. Just the nodes of where they use to be.

If I look under Collaboration / Panels I can see there is a 2D Image but when I unhide them they are all gone.

Any Ideas would really help

Best regards

Nic
