Hi Goeth Roundfort,
There might be some add-ons that might have changed the settings on your Internet Explorer or something changed upon accessing other websites that requires the protected mode making it turn on. The Enhanced Protected Mode isolates untrusted or unfamiliar web content in a restricted environment which is known as the AppContainer.
As a workaround, you check this article's troubleshooting on the Workaroundsection for Enchanced Protected Mode add-on compatibility. Be advised thought that the steps indicated on this article for Windows 7 and up that has Internet Explorer 11 installed.
Please let us know if this resolves your concern.
