While running the analysis on a channel I did a minor update of, Roku declared that there was an Error with the Product Groups, claiming that I didn't have products grouped, which I've had for years.
The first thing I tried worked... simply click on Products -> All Product Groups -> "Group name" -> Click the box for "Group Name" to highlight all products for this group -> Click (-) Remove From Group - > Click on "Channel List" -> "Product Name" to highlight all products -> Add to Group...
You're essentially removing all your products from the GROUP they're in, Saving the group, then going back and adding the products back to the same group. Now the Analysis error goes away.
This bug is apparently just during analysis of a new package and doesn't affect an existing published channel.
