Undefined offset on new content creation

Getting a notice error

Notice: Undefined offset: 0 in sf_entity_export_field_default() (line 1167 of /sites/all/modules/salesforce/sf_entity/sf_entity.module).

On creation of content that is mapped to a SF lead object. The lead is created in Salesforce, and the content in drupal, and I don't know what is causing the error.

Code at line 1167 of sf_entity.module reads:

    default:
      // Unless handled above, use only the first value.
      $result = $data[0][$column];
      break;
