Landing performance card & AoA indexer disagree

[Pixel of Life]

I've noticed that when the AoA indexer shows that I'm on speed, my IAS is around 10 knots slower than the Vref shown on the landing performance card. Shouldn't the green circle AoA correspond to Vref?

Is this with the latest X-Plane 12.1.x? I'll need to take a look, the Vref number speed is going to be slightly above where the green AOA circle sits, but that discrepancy seems a bit more than expected.

Yes, I have the public beta channel selected on Steam. Log.txt says X-Plane 12.2.1-r1-ab13dbf0.
