Hi @thebakerylab, this is Richard - CRO and Marketing expert at PageFly - Shopify Advanced Page Builder.
When you delete pages from your website you have to wait until Google reindex and remove your site. Sometimes it takes weeks for Google to remove deleted pages. Note that to remove Page from SERP, you have to set either 404 or 410 http response.
If you find my comments helpful to you, like it or mark as a solution. Let me know if you have any questions. Have a nice day! Cheers!
