Call me an eternal optimist, but assuming anybody has managed to reach someone high enough in the web support chain to actually get a ticket filed, I imagine they should fix this relatively quickly. The number being wrong in "Expert Mode" is disjoint from the problem of the upgrade-availability indicator showing waitlist only. Since this is affecting both, and thus no Int'l itinerary is shown as upgrade-able, systemwide, that's a gigantic competitive disadvantage.
I imagine IT views this as a small problem, given the other stuff they're doing. But as soon as someone up the foodchain sees/understands what's happening, I have to think it'd become a priority...
