Mine is now showing exactly this same behavior. When I originally tried this (I have the saved screenshots) all values were showing $0. But now just the cost basis and adjustment are showing $0, just like you described. It's definitely wrong and the only way I found to get around it was to manually calculate my cost basis and enter that, though based on your details I suspect that was easier for me than it will be for you.
Anyways, thanks for confirming I'm not crazy 🙂
