WooCommerce Products Admin page (edit.php) is only searching the trash

When searching for products on my WooCommerce site from the backend (edit.php), by default the results are being returned filtered for &post_status=trash.

I want to search all products, not just those in the trash. I think searching all product statuses is the default value, but somehow I guess it has become corrupted?

Is there a line of code I can edit to adjust this default? Or hardcode it to always search ALL.

I've tried looking in edit.php and found line 314 which I think might be controlling it, but edited it to no avail:

<input type="hidden" name="post_status" class="post_status_page" value="<?php echo !empty($_REQUEST['post_status']) ? esc_attr($_REQUEST['post_status']) : 'all'; ?>" />

Any help gratefully received!
