MM's response to my support ticket on this issue:
I did want to let you know that your case had been put in a researching status pending investigation of this issue. Currently, I have checked with our Developers and they agree that this controller message should be there. I am now awaiting their updated information to see if this is something that will be resolved in the future, or if they have other suggested workarounds.
With the additional oversight concerning the GPO5Prefs.xml file, I'm guessing an update will be provided. I hope an update fixes both errors.
