Actually the video was conclusive -- it shows that using memories when programmed correctly on the version of software loaded on the Vision switcher here in our demo room I was able to have no issue. So I would say that having gone into that room looking to find an issue and how to move around it only to find out that it works fine in version 16.1 or later tells me that you need to make sure your Vision is updated to latest version (this is free software contact tech support).
As for your Greyed out Global Store attributes -- Go to the Personality Menu (either from the Left tool bar called PERS) or navigate to it under the Setup Menu Page.
Scroll the List till you find the Global Store Attribute for Memories -- your is going to currently be set to either No Recall or Always. The other Setting is Attributes.
