I'm running Quicken Deluxe2019 for Windows, Version R19.44, Build 27.1.19.44 and am experiencing the same problem others have reported. I set my Tax Planner Filing Status to Married/Joint, scenario Projected and the next time I look at the projected tax I notice Status has reverted to Single. I've reset this multiple times and it keeps reverting to the incorrect status. I noticed someone else claimed this was fixed in R19.34 but this does not seem to be the case. This is REALLY annoying. It isn't fixed yet.
