data browser - editing domain list values / dropdown list

hi there,

i have some troubles with editing domain list values with the data browser. editing/setting domain list values with formview (keyboard) ist no problem. if i try to set/edit some values in the data browser, i can't edit or set some other values. additionally the domain list (dropdown list) isn't shown. for example domain list ID_BPLAN_STAND (including 3 possible values):

  

With the data browser i'm not able to clear or edit the value. the dropdown list isn't shown.

does someone has an answer for this?

thanks and best regards
