Sync data faulty in new devices

[Bigsteve94]

I have used gas bunt for years on an iPhone 5, recently got a 6 plus and attempted to transfer all the data to the new phone but when I sync, my data comes over to the new phone but the vehicle info is gone, it causes all my data to be bunched together under all vehicles. I believe I have 5 or 6 cars setup but that info doesn't come over.

In hopes of fixing it, I go the iPhone 5 and delete sync data, then try to re sync. When that is done, I go to the iPhone 6 and try to sync. Every time I do it I get fuel and service records but no vehicle data. I have an iPad 2 as well and the exact same thing happens to it. I am running the latest version of the app on all devices. I need help adapt as I need to turn my old phone into the company I work for. Let me know, thanks.
