UNS-1 not / missaligned

[Floater]

Hi. 
After quilte some time not flying the C525 I wanted to take her for a few flights last weekend.
The problem: The UNS1 was always misaligned.
The assumed positions were is follows: 
Position EDDV assumed position EDDH
Position EGKB assumed position EGCN
Position EDDM assumed position LOWS
Position EDSB assumed position EDDF
because of this I was not able to enter a flightplan.

The avionics aligned as expected in all situations. 
it makes no difference which avionic setup I select ( default or GNS530).

I also just noticed that the date in the FMS is 1 Month ahead
