_id & _uuid missing

I have the same issue where these tools DATA>Table View and the XLS dataset are not providing all the data available on the server. To solve it, I am using PowerQuery editor but there are some fields like “_id” or “_uuid” which are blanks.

It appears like Power Query Editor gets all the submissions or data that DATA>Table View and the XLS dataset are not getting completed.

I would really appreciate your thoughts,
