Hey there, @robp3. This happens if the employee you're trying to edit the time is deleted or inactive. 

If this isn't the case, I'd like to know what troubleshooting steps did you perform to fix this.

In the meantime, let's try triggering the system by making your employee inactive and active again. You can do this by going to the employee's profile and changing the status in the Actions tab. Don't forget to Save it after making changes.

Then, select Terminated in the Status field and refresh QuickBooks. Repeat the process and make the employee active again.

After that, restart QuickBooks. If the issue persists, let's clear the cache of your default browser to remove accumulated files that may be causing the problem. 

If the same error occurs, let's delete Intuit-specific cookies in your search engine to refresh the website's preferences. Here's how:

1. At the top right, select the More ⋮ icon.
2. Click the Settings option.
3. Choose Privacy and security. Then, Third-party cookies.
   
4. Once done, select 'See all site data and permissions'.
   
5. Enter “Intuit or QuickBooks” in the search field to find Intuit cookies.
6. Go to Delete displayed data or the Trash can icon.
   
7. Refresh Google Chrome for the changes to take effect.
