I am having the same issue and I called Quick books and they couldn't even fix it. If they can't fix it I will cancel my subscription. I am simply inputting expenses for my business that have already been paid in full. Now and then Quickbooks decides to combine some of them. No rhyme or reason. Sometimes it's the same vendor. Sometimes they were paid on the same credit card, Sometimes they were paid on the same day. But in none of the examples above is it consistent. There are others paid t the same vendor, same day, same card etc and are not clumped together. 

This is very annoying. I simply want a running list of expenses, with as many details as possible listed individually. I can input 10 of them and suddenly I look up and is combined several and now says "split" and has added the totals of the items it's combined. 

So far I am no liking Quick books and hope they let me out of my subscription tomorrow if they can't fix it. After 30 plus minutes on the phone she offered to send me articles that might help. I said, not acceptable. I prefer she just explain it to me. She then admitted she had no idea what the issue was. The employee sais she would need to call me back tomorrow when someone was there who might know the answer.
