Did you check that you're installing the correct OS? Here's a link to the support page for your RNDP600U.

Thank you for responding . The unit has been upgraded to v6 and it is recommended never to downgrade versions, so all the v4 files are useless for this system.

Not quite. That advice is limited to OS-6 downgrades - and even there Netgear says is it safe to downgrade minor releases (6.10.7 to 6.10.5 for example, but not 6.10.7 to 6.9.5). As far as converting from 6.x back to 4.x, Netgear offers no advice, as they don't support OS-6 conversion at all.
It is possible to try converting back to OS-4 again, you'd need to put the 4.2.31 image on the USB recovery disk.
Then immediately do a factory reset (perhaps with a spare disk) - as was needed when you converted to OS 6.

You need to make the USB disk using the OS-4 instructions, but put the OS-6 image on the disk instead of 4.2.x.
It's possible that your VPD is corrupted - though it has somewhat different symptoms. If that's the case, then only Netgear can repair it. Although OS-6 isn't supported on your NAS, the mods have often fixed VPDs in the past as a courtesy.

There are the files I used, including 2 OS6 files, and I edited the xml to include them in the USB creator inventory
Here is the creator GUI showing the option I added (PRO)
Does this seem correct for creating a v6.0 recovery USB drive?

No. Prep4tor6 shouldn't be there at all. And you should be using the OS 4.2 recovery tool with an OS 6 image. You shouldn't need to modify any XML.
