I deleted the sidebar off one page and need it back

Hi, This is my first week using WordPress and when I first made my website I was playing around and deleted the sidebar on this page; https://www.barneypartyaustralia.com/test/?page_id=178

If you look at my home page: https://www.barneypartyaustralia.com/test/?page_id=150 there is still a sidebar.

When I click Pages > All Pages in the main menu, I can see I have custom sidebars on both pages, but obviously, when I actually check the page, only the first page actually shows the sidebar and the other doesn’t.

I’ve tried completely deleting and reinstalling the theme and it still didn’t appear, which has led me to believe i may have deleted the code in Appearance > Theme editor but I can’t quite remember.

Thanks in advance for any tips. ??
