Datastore response share cloud storage link

I have created a chatbot using dialogflow cx and I'm using the datastore for answering the questions.

I have 2 type of datastores, one is created using web indexing while other is imported from google cloud storage bucket.

I have also added maximum link 1 option in datastore response in agent responses.

I expect that it should only share the link when it gets the answer from web indexed data, but it is sharing the link of google cloud storage bucket as well when it finds answer from second datastore.

Is there anyway to fix it?
