Remove ":" from select option label(description)

Hello All

I have a requirement to remove the select option description (which SAP displays by default from the field label maintained in the data element),

I thought the best way to achieve that requirement is by passing "space" to the parameter  'I_DESCRIPTION' to the method IF_WD_SELECT_OPTIONS->ADD_SELECTION_FIELD, however, it turned out that SAP still displays the label from the data element inspite of passing space(blank) to the parameter 'I_DESCRIPTION', to overcome this limitation I have created a data element without maintaining any labels this approach worked expect that SAP still displays ":"(colon) as the label, is there any way to get rid of this ":" too?

As shown above, ":" is still displayed as the label of the date select option. I'm also looking for a way to reduce the distance between the last radio button and the select option, any pointers would be appreciated.

Thanks for looking into this.
