There are numerous categories showing up that I didn't have before and that I have not added. Some of these added categories have unusual descriptions. For example, the category "Not Sure" has a description of "Acme Pharmacy". Seems Quicken has been polluting data. I have read elsewhere that this could be due to Quicken Mobile & Web Sync, but I have this turned off and always have had it off. I've hidden the new categories and am now deleting them. I'll watch to see if they show up again, perhaps after the next update.
I am certain that this did not come from my data. Has anyone else seen this?
