S planner problem after 4.2.2 upgrade, help!

[toncol]

My 7.0 tab 2 recently I upgrade to 4.2.2 and since then my s planner has had problems. Whenever I imput an event and uncheck all day to insert a time specific event the date and time fields change if I alter just one of them. It now takes 3 or more attempts to input one date and a start and finish time. Anyone have the answer? Really frustrated as it was perfect before.
