Overwriting the appinstaller file with a new one results in malformed XML

[rooju]

I had written an appinstaller file by hand and then used this app to generate a new one. In the app, I chose to save the file over the manually created one and that resulted in a malformed appinstaller file.

Here is the original manually authored XML

<?xml version="1.0" encoding="utf-8"?>
<AppInstaller
    xmlns="http://schemas.microsoft.com/appx/appinstaller/2018"
    Version="1.0.0.0"
    Uri="_uriremoved_">
	
    <MainPackage
        Name="FiddlerRepack"
        Publisher="CN=Rooju Chokshi, O=Rooju Corp, S=&quot;Washington C=US&quot;"
        Version="1.0.2.0"
        ProcessorArchitecture="x64"
        Uri="_uriremoved_"/>
		
	<UpdateSettings>
        <OnLaunch HoursBetweenUpdateChecks="12"/>
		<AutomaticBackgroundTask/>
		<ForceUpdateFromAnyVersion>true</ForceUpdateFromAnyVersion>
    </UpdateSettings>
</AppInstaller> 

And after I overwrote using the app this is what it wrote. Note the trailing XML after the first closing AppInstaller tag.

<?xml version="1.0" encoding="utf-8"?>
<AppInstaller
  Version="1.0.2.0"
  Uri="D:\sample msix" xmlns="http://schemas.microsoft.com/appx/appinstaller/2017">
  <MainPackage
    Name="FiddlerRepack"
    Publisher="CN=Rooju Chokshi, O=Rooju Corp, S=&quot;Washington C=US&quot;"
    Version="1.0.2.0"
    ProcessorArchitecture="x64"
    Uri="D:\sample msix\FiddlerRepack_1.0.2.0_x64__4vhfqdnqb7ndr.msix" />
  <UpdateSettings>
    <OnLaunch
      HoursBetweenUpdateChecks="0" />
  </UpdateSettings>
</AppInstaller>unch HoursBetweenUpdateChecks="12"/>
		<AutomaticBackgroundTask/>
		<ForceUpdateFromAnyVersion>true</ForceUpdateFromAnyVersion>
    </UpdateSettings>
</AppInstaller>
