Shop title won't go away

Hi,

In order to hide page titles across my site I added this code to my child css, it works everywhere but my shop page …

/*hides the page title and sizes content area space for that title*/
.page h1.entry-title {
    display: none;
}
.content-area, .content-sidebar {
    padding-top: 1px;
}

body.page article header h1 {
      display: none;
}

Please I need some advice.

Thanks.
