Blog posts displaying name and author on Debut Theme after amending settings

[Inesso]

Hi Shopify Community 

I'm hoping you're able to assist with a query on my store: https://themainthingplanner.com which is using the 'Debut' theme

I have published two blog posts removing both the author and publication date in the theme settings (theme>customise>pages>blog>uncheck 'show author' + uncheck 'show date' box

and all works well. BUT my blog posts with author and date are still appearing here: https://themainthingplanner.com/blogs/welcome-to-the-main-thing 

I cannot seem to edit this page and it is not showing up in Header, Footer, Navigation or using customise menu 

Can someone help me locate this page and ensure that it is not visible please!

Thank you so much

Add code assets/theme.scss.liquid Or assets/timber.scss.liquid bottom of the file

.article__author, .article__date {display: none !important;}

Hope this will work for you.

Thanks!
