Date shifts during data entry

[RWTruman]

Frequently when enetering any kind of data (nutrition, workout, wellness etc.) the date will shift from the selected date to some other bordering date. For instance, when entring nutrition data for jan 16, the system shifted to January 15 and failed to accept the nutrition entry. Clicking back to the Fitness Calendar to reselct the proper date, I see that the given nutrition item I was trying to eneter did note record. Then when I try to record it again, the system gives me an error saying I cannot enter duplicate foods. This has happened repeatedly and is very frustrating. Why doesn't your program work?
