Menu item links to incorrect page address

Hello,

I have just reset everything on my blog to use a static home page. I created a page for the posts to be displayed, named https://www.<sitename>.com/blog. The posts now appear there properly. The PROBLEM is with the menu item I have created to link to that page.

Instead of sending me to …./blog it sends to …./blog-2. This is a problem, because there isn’t actually a blog-2 page. I have rechecked my slug on the /blog page, and I have made sure no other /blog or …/blog-2 page exists. There was a time earlier today when I did have a page with a blog-2 slug. But I have deleted everything and started again twice now.

I have also wiped the home and the blog pages, deleted my .htaccess file, rebuilt the pages, reset the permalinks, and deleted and rebuilt the menu. But whenever I recreate the desired menu item, it still sends me to …/blog-2.

It seems like the menu won’t stop remembering that it once linked to blog-2, or that the list of pages that can be selected for a menu item won’t refresh, and thinks any Blog page is blog-2. But I have no caching plugins installed and I have cleared browser cache several times.

I would really appreciate any help here. Thank you.

And the menu item in question is the BLOG item at the far right of the top menu bar. The actual page where blog posts display is: https://jonathanmenon.com/sandbox/reverie/jenna/blog
