Inability to export data as '.csv' file in pgAdmin4

I am using pgAdmin4, which I downloaded and installed for Windows from the below link : "https://www.postgresql.org/ftp/pgadmin/pgadmin4/v1.5/". So now, when I query the database, I'm able to view the query result, but I'm unable to download it as a .csv file, as nothing occurs/happens when I press on the button, containing the 'Download' symbol. 

I have attached the pictures for reference.

'Download.csv' : This is how it looks like when I press the download button, that you can see in the image. It is surrounded by black solid circle. And after that, nothing happens.

Can you please suggest a quick fix for this problem, as it really is cumbersome for me , not being able to download the dataset.
