Hi, I am using DIET Classifier for entity extraction. However it is extracting an entity twice whereas both combined is the actual entity. Please let me know how to resolve this. Below is the output:

Received user message 'get site Washington DC' with intent '{'name': 'show_sites', 'confidence': 0.9747471809387207}' and entities '[{'entity': 'sitename', 'start': 9, 'end': 19, 'confidence_entity': 0.7346358895301819, 'value': 'Washington', 'extractor': 'DIETClassifier'}, {'entity': 'sitename', 'start': 20, 'end': 22, 'confidence_entity': 0.5150449872016907, 'value': 'DC', 'extractor': 'DIETClassifier'}]'
