How to delete pages from website?

Greetings from TicTalkers Toastmasters Club 6348!

I am the VP of Membership and would like to help our member and guests navigate a friendly, less-cluttered website at 6348.toastmastersclubs.org
We have many pages that were helpful to us in the past, but no longer contain wanted, needed, or relevant information. For example:
- Youth Leadership Program
- Recent Meetings/Events
- About TicTalkers
- Club Calendar
We're combining the info that might have been listed there to where it's more appropriate and visible, for example, our web page, and communicating some of the info instead via Facebook and LinkedIn, where the majority of our members and guests are more likely to frequent and engage.
I tried going to the "Custom Web Pages" tab and clicking on "Delete" (and then saving) as well as moving pages to the "Unlisted Pages" but nothing seems to work. Deleting them resulting in the link still being there, but clicking on it just results in stalling. When trying "Unlisted Pages," I still see the page listed.
I appreciate your guidance! Thank you in advance for your awesomeness!
Sincerely,
Caroline

I don't see any of those pages in your left menu.

Brian, thanks so much! I was able to receive assistance from someone who has much more technical expertise than I do. He was able to assist, but I really appreciate your confirming the changes we made. Thanks again! Keep being awesome and take care!
