Spreadsheet updates not accessible in App

I am creating an App using the Spreadsheet component.
The API key has been setup correctly and am able to extract some data.

This is the table. The block I am using are

From what I have checked, only the first and last column are accessible
in the App. The others are not “visible”.
Incidentally, I had initially created the spreadsheet using only those 2 columns.
I am wondering if there is some sync issue where the spreadsheet updates
are not visible in the App.

Any help is appreciated. Thanks!
