BlockExecution not working as expected

i am using powershell app deployment toolkit 3.8.2

i have the below line.

Show-InstallationWelcome -CloseApps ‘winword,excel,outlook,powerpnt,lync,mspub,onenote,msaccess’ -AllowDeferCloseApps -DeferTimes 3 -CheckDiskSpace -PersistPrompt -BlockExecution

once, the installation started and i purposely click outlook or word application, it will pop up below message. it does not show the message that outlook application is blocked during the installation.

This is a known issue at the moment due to a change related to the CVE that was reported to us. We are working though possible fixes and should have something very soon.
