selected value in DROP down by KEY

Hi Team,

Hi  Team i have created one Dropdown by Key

and set the values based on the

lr_visa_node_info->set_attribute_value_set( name = 'VISA_TYPE'

     value_set = it_value_set_reports ).

and in Dropdown it shows the text it's fine But when i selected the text the input value become 'value'

In the below image In dropdown it show the Text but when i selected the value the value becomes 22 means KEY.

Thanks
