Two steps to fix this.
1. Create a new cemetery for the Opdyke Park Cemetery.
-- Open Cemetery Map and navigate to the location of the Opdyke cemetery. Down at bottom, click on Add a New Cemetery and follow the guidance to create the Opdyke Cemetery. You might want to add in the description a note that this might have been the potters/poorhouse site, if you are sure of the information. Check with locals on this "history".
-- Once you have created the new Opdyke cemetery, you can move those grave records to it:
2. Open the Shiffler Cemetery, and navigate above it to the pins that are at the Opdyke location.
3 Click and open each of the pins in the Opdyke park location, one at a time, iin the Transcription Window. Change the Cemetery location from Shiffler to Opdyke. Be sure to hit the UPDATE and Save after each cemetery change.
It should not take too long to correct all these to the right location.
