Display XY not letting me select an X field or a Y field

SLouq

I am stumped. I've used this tool before and it always worked but now it's not.

I am trying to Display XY data in my map. I have an Excel spreadsheet which has lat/long coordinates in it split into it's own column but when I open the Display XY Data for the Excel table in ArcGIS Pro, it is not giving me an option to select an X field or a Y field. 

 

Why is this?

open the table properties and ensure that the field is numeric (float or double)
