Not working correctly grouping in views

After the module "date" from "7.x-2.0-alpha3"(datestamp = "1303821715") to 7.x-2.0-alpha4, It's no longer work correctly grouping on the field.

In views I have data with 3 column: title, date, link2download in the "views".

Format field "date" is default - dd.mm.yyyy hh:mm:ss (timestamp).
For grouping by year I convert field "date" into YEAR :
1)Add new format with admin/config/regional/date-time/formats/add - Y (php) and call them "Year"
2)In the view select "Year" (Choose how users view dates and times:) for field "date"
3)And in "admin/structure/views/nojs/display/news/page/style_options" select group by field "date"

In views field "date" converted fine, i see "2010", "2011". But view group by timestamp, not by "Year"

P.S. Sorry for my english
