I just started using Quicken yesterday. Got most of my accounts set up to pull data automatically. Two weren't supported and I have to handle those manually (will have more questions on those later). Everything was looking reasonable yesterday. Today I was prompted to update to the new April version, with the net worrh card, and that's making something look very odd. There must be some hidden transactions about 15 months ago, and another about 7 months ago that adds and remove millions of dollars. It doesn't show up in the All Transaction lists. It doesn't show up as a line item in the calender view, but does show up as a changing total in the calendar view. It seems to be some artifact — I've never made a pair of transactions like that. And it doesn't really matter, but it does make the net worth chart look really odd. As it predates the date on any of the account I had to enter manually, I don't think its related to those.
And it makes me wonder what else I did wrong when getting set up that will surprise me later.
