Unable to set business hours

Unable to set business hours

Hello,

I was trying to set the start of the week to Monday, company-wide.  I found the tutorial that shows going into setup -> General -> Company Details -> Business Hours

However, when I click on that tab, nothing happens.  I have tried on multiple devices and browsers.  All the other tabs (such as holidays) work fine.  It is just the business hours.  It takes me back to the main Company Details page.

I am the only user, so permissions should be an issue.

Any help would be appreciated.
