There is a bug in the new Watchlist feature. It is showing the wrong daily percentage change for securities at the top of tthe window. Here's an example of a screenshot of a Quicken Mac Watchlist screen for the security "ONEOK":
Note that this stock is down 49¢ to $80.53, a decline of 0.6%. But Quicken is showing a decline of 49%.
