Dear amanV,
you would have to insert in the view one entry for each parent title you want to retrieve, so you would have the parents titles.
[wpv-post-title id="$cpt-parent-1"]
[wpv-post-title id="$cpt-parent-2"]
Please let me know if you are satisfied with my answer and if I can help you with any other questions you might have.
Regards,
Ana
