Error with specific blog posts

Hi,

I have a weird issue where 2 blog posts will not display returning empty content.

In my post.php I do

$post = perch_blog_custom(array(
          'filter'        => 'customPostSlug',
          'match'         => 'eq',
          'value'         => perch_get('s'),
          'skip-template' => 'true',
          'return-html'   => 'true',
      ));

and then print it with

<?php echo $post['html']; ?>

When going to the url using the customPostSlug I get 404 while when using the default postSlug I get an empty $post. Here the debug when getting the empty $post. (the "Undefined offset: 0" is because I use $post[0] in post.php)

Some notes

• The two posts with the problem initially had the same title and same postSlag. I changed the titles and even delete one of them and rewrote it with different title and slug but still having the problem.
• There are around 130 posts, I tried many of them and the problem only appears with these 2

Do you see the problem in my code? What else should I try?

Thanks a lot!!
