Answer 1

You don't need to call wp_reset_query() here, because you're not modifying the main query. Instead, call wp_reset_postdata().

You only need to call wp_reset_query() when modifying the main loop via query_posts() (which you shouldn't do, anyway, so you should never need to call wp_reset_query()).

But new WP_Query(), with a properly instantiated loop - i.e. one that calls the_post() - will stomp on the $post data for the main query. So, after closing your custom WP_Query() loop, call wp_reset_postdata() to restore $post data to the main query.

Answer 2

Try changing

<?php wp_reset_query(); ?>

to

<?php wp_reset_postdata(); ?>

As codex says "After looping through a separate query, this function restores the $post global to the current post in the main query"

Instead wp_reset_query destroys the previous query used on a custom Loop.
