Had this issue for years and finally thought to ask.
I manually enter transactions at times from scratch for my bank account. I have an issue that pops up at times during this when splitting a transactions' categories - and it typically seems to happen with splitting grocery purchases, that after one or two entries in that split of grocery items, Quicken defaults to the 'Personal Income' category as opposed to the 'Food' category I was in up to then, and I have to manually go in, select 'Food' again, and subcategory 'Groceries' and carry on where I was.
Absolutely no idea why it does this.
Please, if anyone even has a hint of what is going on.
Thanks
