Hi @Mark Johnson ,
Suggest you applying SP3 to SQL 2016. You can get it from here.
If the issue still exists, please you can start to troubleshoot this issue from Oracle side. May be you can use SQL server migration assistant for Oracle tool to compare the converted objects to the original objects to identify potential problems, and address them based on the recommendations. After that you may can replicate the data successfully. Please refer to this MS document to get detail steps.
