Why are there two vehicles listed as primary, and how do i delete one?

Hi there, 

I'm glad to learn you're taking advantage of the QuickBooks Self-Employed Mileage feature. This feature allows you to track personal and business trips with ease. The goal is to help you estimate your business travel so you can make accurate deductions.

At this time, the ability to delete an added vehicle is only available in iOS. I encourage you to check out this article with more info: About the Trips page and vehicle info settings.  I know how useful this feature is to you and I encourage to forward this to our engineers by clicking the gear icon and looking for Feedback. New product ideas and improvements are largely based on the feedback we get from users like you. In case you have other questions, feel free to contact our support team using this link here or leave a comment below. Otherwise, enjoy the rest of your week.
