Formatting issue

I'm having an issue with the formatting of the calendar.

As you can see in the image the previous button is too close to the next and for some reason the event times for long events are getting pushed below and getting cut off. I could surly fiddle with the CSS and fix it but then when there is an update to the module I'll lose my fix and have to do it again every time. Is there a built in setting to the mod that could solve this issue for me?
