Get permalink issue for custom post type

Hello,
I am using wordpress version 4.6 and getting issue with get_permalink($ID).

My code is
<?php echo get_permalink(826) // ID of custom post ?>
Output : https://www.seodecollageimmediat.com/disclaimer-sur-la-traduction-du-livre/

Link showing on edit post page below post-title is : https://www.seodecollageimmediat.com/livre-referencement/disclaimer-sur-la-traduction-du-livre/

Why function get_permalink() returns different result then original.
Please help me out for this.

Thank you.
