MSIs not uninstalling after installing Base bundle + Patch bundle

[kalyani1217]

Question

We have a Base bundle (WiX v6) that installs two MSI packages.

Currently creating a Hotfix bundle that contains only MSP patches for those MSIs.

Installation flow:

Install Base bundle (MSI1 + MSI2 installed)

Install Hotfix bundle (MSPs applied successfully)

Uninstall bundles

Issue:
Only the bundle ARP entries are removed, but the MSI packages remain installed. The MSIs are not being uninstalled. Permanent="yes" is not set anywhere.

MSIPackage:

 <MsiPackage Id="DemoAppAdvance"
             Compressed="yes"
             Name="DemoAppAdvance"
             SourceFile="..\DemoAppAdvance.MSI\Bin\$(var.Configuration)\DemoAppAdvance.msi"
             DisplayName ="$(var.DemoAppAdvanceProductName)"
             Vital="yes"
             ForcePerMachine="yes"
             EnableFeatureSelection="yes">
   <Provides Key="{238B9028-476C-4238-9A6E-642552242FC6}"/>
   <MsiProperty Name="ARPSYSTEMCOMPONENT"            Value="1"/>
   <MsiProperty Name="INSTALLFOLDER"                 Value="[INSTALLFOLDER]"/>
   <MsiProperty Name="BUNDLE_PROVIDERKEY"            Value="[WixBundleProviderKey]"/>
   <MsiProperty Name="ARPCONTACT"                    Value="Customer Support"/>
   <MsiProperty Name="INSTALLLEVEL"                  Value="1"/>
   <MsiProperty Name="ARPCOMMENTS"                   Value="$(var.DemoAppAdvanceProductName)" />
   <MsiProperty Name="REINSTALLMODE_TYPE"            Value="[REINSTALLMODE_TYPE]" />
   <MsiProperty Name="ADDSHORTCUT"                   Value="[ADDSHORTCUT]" />
 </MsiPackage>

MSPPackage in patch bundle:

 <MspPackage Id="DemoAppAdvance"
            Compressed="yes"
            Name="DemoAppAdvance"
            SourceFile="..\DemoAppAdvance.MSP\Bin\$(var.Configuration)\DemoAppAdvance.msp"
            DisplayName ="$(var.DemoAppAdvanceProductName)"
            ingr:ValidateMsiForSignature="yes"
            Vital="yes">

       <Provides Key="patch Id" Version="$(var.ProductVersion)"/> 
        <MsiProperty Name="ARPSYSTEMCOMPONENT"            Value="1"/>
        <MsiProperty Name="INSTALLFOLDER"                 Value="[INSTALLFOLDER]"/>
        <MsiProperty Name="BUNDLE_PROVIDERKEY"            Value="[WixBundleProviderKey]"/>
        <MsiProperty Name="ARPCONTACT"                    Value="Customer Support"/>
        <MsiProperty Name="INSTALLLEVEL"                  Value="1"/>
        <MsiProperty Name="ARPCOMMENTS"                   Value="$(var.DemoAppAdvanceProductName) HF $(var.HFNumber)" />
        <MsiProperty Name="REINSTALLMODE_TYPE"            Value="[REINSTALLMODE_TYPE]" />
        <MsiProperty Name="ADDSHORTCUT"                   Value="[ADDSHORTCUT]" />
      </MspPackage>

Thanks for the help!
