Date evaluation in NAV 2013 R2 - Swedish version

Hi,

we have some problems on our NAV 2013 R2 clients.

When you type YYMMDD for example 140101 it turns into 14010101 in all date fields in NAV, it shoud turn into 2014-01-01

If you type 14-01-01 it works ok and turns to 2014-01-01.

Anyone had this problem?
