delete the data from record

 Hello,

I'm a beginner, I have created a form and connected it to the data store and successfully writing the data to data store. Now in records I have many duplicates, I hate to delete them. How to do it? I've also come across using a  Delete from "Data Store Entities" but in my CDT I have an ID and primary key for it. But its never showcased under records. Thus how to delete a record now. 

Please refer to below screen shot

None of them are represented by an ID, but in Name hyperlink there is the Summary, though how can I delete the record. It should also be totally deleted from mysql DB.

Any suggestion would be highly appreciated...!!
