Hi Jinho,
This is very odd, the plan should not be able to be "protecting" state at both sites. Can you please double check that:
1. Your code is connecting to both sites (check that you connect to different IP addresses)
2. You are looking at the same plan (it might be a bit tricky to differentiate between /plan and /folder/plan)
Let me know if this helps (or more likely does not help) so we can discuss next steps.
Best regards
Stefan Tsonev
