Changing name under Device Info

I changed the name of my iPad using. Settings--> General-->About-->Name. This displays what I want. So in Find my app this is the name showing up. However, in the iPad when I click on Settings and then the pic up top with my Apple ID under this the device information list at the bottom the iPad name is listed differently. The one there is the name of my old iPad that I used to download stuff onto my new iPad. Problem is this name is the name of my works iPad which I returned when I bought my own.
