I had the same thing. I got this response from them on March 6th.

That's not a problem. It's just a small (albeit annoying) bug. The only way to actually see what you're missing (if anything) is to go to Help>What add-ons do I have?. It'll probably say that you're missing two soloist discs but that's also nothing to worry about -- they're not included in any of our packages.

But I noticed just now after reading your post that I don't see that listed anymore, i.e., it doesn't show the missing items, it just lists the various choices under the categories. I presume it changed with build 461 since, as they say, it's actually misleading, a glitch.
