symfony - How to delete a child who has left a collection to another child?

I have a problem.

I have a Newsletter entity that has an OneToMany relationship to the NewsItem entity. My NewsItem entity also has an OneToMany relationship to the NewsSubItem entity.

My problem is that with my current code, I can't delete a NewsSubItem correctly.

Either I manage to delete a NewsSubItem that causes a total deletion of my NewsSubItem or I can't delete any NewsSubItem at all.

Here is my current code:

Newsletter -> NewsItem

/**
 * @ORMOneToMany(targetEntity="NewsItem", mappedBy="newsletter", cascade={"persist", "remove"})
 * @AssertValid()
 */
 private $newsItems;

/**
 * @ORMManyToOne(targetEntity="AppEntityNewsletter", inversedBy="newsItems")
 * @ORMJoinColumn(name="newsletter_id", referencedColumnName="id", onDelete="CASCADE")
 */
 private $newsletter;

NewsItem -> NewsSubItem

/**
 * @ORMOneToMany(targetEntity="NewsSubItem", mappedBy="newsItem", cascade={"persist", "remove"}, orphanRemoval=true)
 * @AssertValid()
 */
 private $newsSubItems;

/**
 * @ORMManyToOne(targetEntity="AppEntityNewsItem", inversedBy="newsSubItems")
 * @ORMJoinColumn(name="news_items_id", referencedColumnName="id", onDelete="SET NULL")
 */
 private $newsItem;

An idea ?
