Why is Proseries giving error alert for missing basis for business auto even though standard rate used?

I have a simple Schedule C client who just has a few business miles.  I have always just used the standard rate and fill in just enough of the Auto Worksheet to get the deduction for her miles to her Schedule C.  I'm getting an error message that I need to enter a basis for the vehicle.  There's no reason for me to do that as I have always used the standard rate for this business and this vehicle.  Anyone know how to clear the error?  This is a new error for me for 2025.

Wow that did it - thanks Jim!  Such a simple solution that I may never have found even though I've used this program for many many years.  New thing in 2025???

I went through the same thing you did after many yrs. usage. By accident I found the solution you received. Once I put in zero fo the basis and that worked it to standard mileage.

seems there’s some new 2025 quirks!
