dynamic range in combo box

I want to use a dynamic range in a combo box. The formula seems to work fine. When I inspect the range by clicking on the formula field in the 'name manager', I can see the field expand or contract, as expected, when I add or delete data.. I am using =OFFSET(Applicants!$A$1,1,2,COUNTA(Applicants!$A:$A)-1,1). The formula appears to be doing its job.

I typed the name into the ListFillRange field of the combobox. When I add names into the field I now lose the bottom of the range in the display of the combobox. In other words, once in the combobox, the dispalyed field is not dynamic. But the field in the data page expands just like you would expect.

Is there a solution. Thanks for your help.
