C819-4G-LTE-G 4G Connection lost after reboot

I have the connection working perfectly, but upon rebooting there is an error in the config for the LTE data profile entry.  The router then discards this line and continues to boot.  The LTE line is missing from the config after the reboot has completed.

After it has booted, I need to re-add the data profile, shut/no shut the dialer & cellular interfaces, then the connection comes back up.  I've copied the relevant parts of the working config below (this is the config prior to rebooting).  Then after a break I've posted the errors that occur when I reboot the router.  Obviously I'm writing changes to memory before rebooting.

It's not the register that's wrong.  That is loading correctly (0x2102).

Also, here is the version/IOS: "flash:c800-universalk9-mz.SPA.155-3.M.bin"

My guess is that it's the IOS.  But we had a Cisco engineer in to our office and he put this one on it - he couldn't get it working either, although he hasn't followed up with us yet.
