Hi,
You cannot do it above. Because the combobox binding to a same source, so if you change one Item on a Record, it changes all of them. You can edit your code like below:
<Page
x:Class="comboboxtest.MainPage"
xmlns="http://ift.tt/w9rHWX;
xmlns:x="http://ift.tt/zZkFEV;
xmlns:local="using:comboboxtest"

xmlns:mc="http://ift.tt/R4RR6u;
mc:Ignorable="d">
<Page.Resources>
<!-- TODO: Delete this line if the key AppName is declared in App.xaml -->
<x:String x:Key="AppName">My Application</x:String>
</Page.Resources>
<!--
This grid acts as a root panel for the page that defines two rows:
* Row 0 contains the back button and page title
* Row 1 contains the rest of the page layout
