Created Unassigned: 3.0.9 Show-InstallationWelcome cannot use AllowDefer and CloseAppsCountdown at the same time [48]

First, thanks for all you do!!!

Using 3.0.9 (from mostly working 3.0.8) -

I get error on client:
"You cannot use AllowDefer and CloseAppsCountdown at the same time (at Show-InstallationWelcome, <path>: line 2327 at <ScriptBlock>, <path>" Path's are jsut local to sccm cache...

I don't see this restriction in documentation or examples, and I've been using the same .ps1 script since 3.0.7 with no issues. Documentation says:

CloseAppsCountdown - Option to provide a countdown in seconds until the specified applications are automatically closed. This only takes effect if deferral is now allowed or has expired.

AllowDefer - Enables an optional defer button to allow the user to defer the installation.

-------------------------- EXAMPLE 7 --------------------------
C:\PS>Show-InstallationWelcome -CloseApps "winword,excel" -BlockExecution -AllowDefer -DeferTimes "10" -DeferDeadline "25/08/2013" -CloseAppsCountdown "600"
Close Word and Excel and prevent the user from launching the applications while the installation is in progress.
Allow the user to defer the installation a maximum of 10 times or until the deadline is reached, whichever happens first.
When deferral expires, prompt the user to close the applications and automatically close them after 10 minutes.
