Thanks for reporting this. We are currently investigating an issue where some tables are being returned as null. I will update this thread once a fix is released.
An update to this one. If you train a new form processing model, you should now get tables values returned.
For your existing model, a fix will be released beginning of next week that will solve the issue.
