Adobesign - Salesforce merge fields error when sending an Agreement

Adobe Sign for Salesforce error:  I am getting the following error when sending any Agreement using Merge fields:

"System.QueryException duplicate field selected: echosign_dev1__Contract__c Class.echosign_dev1.MergeMappingProcessor.loadFullAgreement: line 413, column 1 Class.echosign_dev1.MergeMappingProcessor.: line 52, column 1 Class.echosign_dev1.EchoSignApiUtilities.processMergeMapping: line 1131, column 1 Class.echosign_dev1.EchoSignApiUtilities.doSendDocument: line 951, column 1 Class.echosign_dev1.EchoSignApiUtilities.sendDocumentInteractive: line 865, column 1 Class.echosign_dev1.AgreementComponentController.sendAgreementData: line 1367, column 1 413".

The field "echosign_dev1__Contract__c"  exists both on the "Agreement template" object and the

"Agreement " object.   Is that the problem?    If so.....how can I change this since they are managed objects?

Thanks for your help!
