Save in meta (custom field) does not work

I have resolved the issue in my case, Its working fine for custom post type custom meta fields, but still in repeater case the example provided in documentation is not working in my case

$repeater = get_lzb_meta( 'uni_products_detailmeta' );
            foreach ( $repeater as $inner_control ) {
              ?>
                <p><?php echo $inner_control; ?></p>
              <?php
            }

by print_r if found this row data
%5B%7B%22uni_product_name%22:%22Chinese%20Saree%22,%22uni_product_price%22:%22251%22,%22uni_quantity%22:%2211%22%7D,%7B%22uni_product_name%22:%22Banarasi%20Saree%22,%22uni_product_price%22:%22351%22,%22uni_quantity%22:%227%22%7D%5D

But I am not sure how to explode it and display individual field value in a table for example.
