I am experiencing this problem, as well. We recently transitioned to QBO from QBDT and my data reports are missing data. The reporting tool n QBO is not as intuitive as QBDT - to my dismay, as it appears super-intuitive, but the coding/logic behind the window is somewhat of a muddled mess.  

As we use transaction detail reports for our cost analysis on jobs, I am very concerned that the lack of integrity in the reports will be problematic for our analytical purposes.  Unreliable data does not make for good accounting.
