menu links point to wrong page

Hello,
I’m having an issue I just noticed with links going to wrong pages in the self-hosted wordpress site I run (chaindlk.com)
For example the “interviews” menu item which points to chaindlk.com/interviews should go to a page that has a link of interviews (which I do see among my pages and whose shorting IS indeed set to chaindlk.com/interviews) and yet it just posts to a list of posts… This worked for years and stopped working recently, in the last week or two… not sure what triggered it, maybe a wordpress update? I tried disabling my speedlite cache but that didn’t fix it… can somebody point me in the right direction please?
Thanks a lot!
