I've noticed this once or twice, but not really been concerned since I could easily access the information otherwise.
If using the "Get HMRC Data" option in Digita, and it gets, for example, 3 sources of income. This is indicated on the schedules, and you open each to accept or reject. However, after opening one schedule, the HMRC will vanish from the others as though it was never there, and it can't be retreived again.
Is this a bug, or am I doing something wrong?
