True/false question import answer is always "correct"

Hi,

I am not able to import anymore true/false questions, the answer option is not imported.
Tested with Quiz Question Import 1.1 and 1.0 versions.

Modules installed:
Feeds 2.0 beta 1
7.x-4.0-rc1 (tested also with beta4)
Quiz question import 1.0 (tested also with 1.1 and latest patches)

Importing worked fine but after installing latest version of feeds -module (7.x-2.0-beta1)
the answer option is not imported (The answer is always "correct" so either nothing goes to database or always value "1" goes..).

Column in the CSV file is "answer" and the values are either "0" for false and "1" for correct.

I will next test this with older version of feeds if possible
