Unable to Properly Uninstall Application after Slipstreaming Patch in Bundle

[KarthikChandran303]

Hi all,
I have a Bundler that includes a "MainInstaller" msi package and a patch (which is slipstreamed) within a Chain like this:

<Chain>
<MsiPackage Id="MainInstaller" SourceFile="$(var.MainInstaller)" bal:DisplayInternalUICondition="WixBundleAction >= 0" Visible="no" Vital="yes" Permanent="no"/>
<MspPackage Id="Patch" SourceFile="$(var.Patch)" Vital="yes" After="MainInstaller" Slipstream="yes" Permanent="no"/>
</Chain>

Uninstalling the bundle only removes the slipstreamed patch. Any ideas as to why the main installer is not being removed?

I am also providing a part of my log which gets generated when I uninstall:

Thanks for the help!
