I contacted Yoast SEO and they told me to go to this link – https://kb.yoast.com/kb/how-to-check-for-plugin-conflicts/. I installed the Health Check & Troubleshooting plugin. I updated my PHP for the website, started using the troubleshooting tab, and started enabling each plugin one after another. Of course, the very last plugin on the list was YOP Poll by “yourownprogrammer”, and that plugin was the one that was making the Yoast SEO plugin display incorrectly on the backend.

I just disable and deleted that YOP Poll plugin, and everything seems to be working great right now.
