Currently UI doesn't wait for the result to be returned , it directly passes 6 request at a time to the api , It works on a strange way sometimes query is duplicated , sometimes overlapped ! It is not passing one query at a time and waiting for that query to be returned and pass another query ! We need to debug it in order to block overload on database side
