SFCs not uploading from Freelance to 800xA

We recently installed a new AC900F on an existing Freelance (2016) system. The system has an 800xA layer that is used to interface with Batch. We went through the steps to synchronize the Freelance tags with the 800xA. All the Function Blocks and Variables synchronize to the 800xA OK for the new controller, except the SFCs. What could be wrong? (The SFCs for the old controllers are OK.)
