Hi dwsmithjr,
We have a similar issue reported by another customer and are investigating the scenarios and environmental causes to reproduce/find a fix. Could you get in touch with the Support with the following information?
1) Name of the node - whether it occurs with all the node or for a particular node/sets of nodes. Does the node contain a "dot", by any chance?
2) Do you see any error message when you try to upload partial changes (we had this reported and this appears to be a bit related to the actual error you had mentioned, that is why).
3) Your environment details
