Calendar Module - lot of questionmarks

[Wurzelxquadrat]

Hello

Since i made a Update i have some trouble with my calendar module and i could not find the problem.

There are three points i would appreciate to get some advices.

1. underneath the clock i have a weeknumber in brackets - i do not know where it is comming from ?
2. there are two calendars i am showing - 1-Private / 2- Birthdays - for me it is not clear where i can setup the symobls and the distance from the left side.

I am not realy familiar with html ;-( can somebody explain to me at least in which direction i have to search ?

Thanks in advance
