Dropdown Slicer

Hi there,

I currently have a dropdown slicer that is showing a two different fields. For this example, the field names are Letter and Number, the format the way that it looks is:

A

    1

    2

B

    3

    4

And when I select 2 for example the display on the Dropdown menu shows "A (Letter) + 2 (Number)". I want it to just display "2" in this example, how do I do this?

Thank you in advance!
