Hi there,
You've come to the right place for help. I'll be happy to give you a hand with this so you can get back to doing what you love.
The alerts you're getting may be related to an employee you may have excluded on your previous payroll. To make sure this isn't affecting your payroll in the long-term, could I have you use a private/incognito window to see if you're seeing this error. If so, feel free to reach back for further assistance. If you don't see this message while using a private/incognito window, you should be good to go with your payroll. You can continue running it as normal.
Let me know if you have questions. I'll be one message away.
