Buy it now and Powersellerstatus

Hello together.

I've a little problem with my registered Sandboxusers.
I'm not able to use the buy it now option or list an item with a quantity more
than 1.

I know that the user must have a minimum of positiv userratings so i created a
user with the maximum stars of 1000.

But I'm not able to use this options. I also had a look at
https://ebay.custhelp.com/cgi-bin/ebay.cfg/php/enduser/std_adp.php?p_faqid=226
 when someone told me but the listed users are not able too.

So my question is how to get an user who is able to list such auctions.
