Preview Calendar Today issue

Hi there,
Sometimes I’ve been noted that the preview calendar doesn’t update. I doesn’t happen all the time but it does.

Now, I know that this is easy to fix, just click over the right arrow and the correct day will show but it will be very usefull to fix this bug. Also I’ve noted the “Agenda” mode, which is grate for me, sometime doesn’t get update and this is why I’m not using it and I using the Calendar preview.

Could you please take a look at it?
