Remove Double Title

Hello.
After child theme creation, I’ve inserted in attitude-child two new pages that are: page_no_page and page_slider.
Page_no_page is the homepage‘s template and page_slider is every other pages’s template except gallery page
The other pages use the standard template from attitude theme.
How can I remove the grey title from these pages?
I want to view only entry-title, like in gallery page.
Could you help me, please?
