Calendar Page Toolbar With Wrong Position

Hi guys, Here I am (again) with a calendar issue :grimacing:

I set my page exactly like the one in kitchen-sink. Now reading the docs I saw I could set a toolbar to easily pick the month and year.

But when I set the parameter toolbar: true in app.calendar.create, the toolbar CSS is messy.

Wich CSS should I change to make this right?
