    Please try if this works:

    elseif ( is_array( $meta_box['pages'] ) && count($meta_box['pages'])
>= 1  )

    Try:

    elseif ( is_array( $meta_box['pages'] ) && count( $meta_box['pages'] )
=== 1)             $type = is_string( end( $meta_box['pages'] ) ) ? end( $meta_box['pages'] ) : false;

    Your code did not work because === 1 was inside the count() function call: count($meta_box['pages'] === 1), and a comparison returns a bool. Here, I have changed it to count($meta_box['pages']) === 1 which gets the number of elements in the array, and checks if it returns 1.

    The closing parenthesis of count is in the wrong position. You are actually passing a boolean to the function, because "$meta_box[‘pages’] === 1" will return true or false. Your code should be:

    count($meta_box['pages']) === 1
