Why am I getting the error 'Could not find all of the specified destination fields in the lookup table.' for conf 'splunkd' in Chargeback Analysis for Splunk on all clustered peer indexers?

We are getting the following error on all clustered peer indexers after installing the Chargeback App.
I have run the back-fill searches on all search heads as the App installation instructions suggested. Still getting the error.

Error 'Could not find all of the specified destination fields in the lookup table.' for conf 'splunkd' and lookup table 'customers'.

Can someone suggest a resolution to this?
Thanks

Change the lookups (all 3 places) from global to App.

Thank you!
Now the error still shows within the Chargeback App.
The error has disappeared from Search and Reporting App though.
