[Theme: Minimatica] Remove "Pages" Title of Sidebar

Hi,

Can anyone help me…I cannot work out how to remove the word “pages” from above my sidebar menu on my site. I am using the Minimatica theme, so have tried most of the advice from these past posts. My website is: https://www.am-originals.com

and the link to my sidebar.php page is:
https://www.am-originals.com/wp-admin/theme-editor.php?file=sidebar.php&theme=minimatica

Please, I have spent days trying to figure this out and am sure it is a simple problem. Have posted the query on the Minimatica forum but no-one got back to me.
