I have discovered that the issue I have been experiencing with the "weeks" selection buttons in the planner not working (week view would not come up) is tied to the "event stack" option when I am configuring the planner. When I select event stack the weeks buttons do not work. In the same planner setup if I change to "Time Block" and regenerate and push the problem goes away. The issue is repeatable (for me anyway) by changing back and forth. Bad with event stack, good with time block. Hope that helps.
