The NullValue property of the NumericUpDown is of type string and accept strings, so you should set it to empty string in order to show nothing:
<telerik:RadNumericUpDown NullValue="" />
However thanks for bringing this to our attention, I have logged it our internal backlog so it will be considered for fixing in the feature releases.
Hope this helps. I have also updated your Telerik points for your involvement.
