Facebook AppID Error from Appointments+

Receiving an APP ID error when using Appointments+. No other plugins running. With Appointments+ off do not get the error.

Here is the error:

"error": {
"message": "Unsupported get request. Object with ID '170713183042873' does not exist, cannot be loaded due to missing permissions, or does not support this operation. Please read the Graph API documentation at https://developers.facebook.com/docs/graph-api",
"type": "GraphMethodException",
"code": 100,
"fbtrace_id": "BUXLiNYbnDx"

There is apparently an APP ID being called within Appointments+ which does not exist.
