ArcGIS Pro - Join concerns

I have been struggling with Joins on ArcGis Pro.  After some unexpected and undesired results using Spatial Join, I tried what I thought would be a simple join using public data.  Unfortunately, the result shows zeros for rows where I know there is data.

 

I used Excel to calculate the population and households for US counties, the results of which are in the attached CSV file.  This file has the same GEOID values as the cb_2017_us_county_5m shapefile from the census.gov site (https://www2.census.gov/geo/tiger/GENZ2017/shp/cb_2017_us_county_5m.zip).  I used the Join Field data management tool with the following paramters:

 

Join Field Parameters:

  • Input Table: cb_2017_us_county_5m
  • Input Join Field: GEOID
  • Join Table: county_pops_hh-2017a.csv
  • Output Join Field: GEOID
  • Join Fields: Pops2017;Households2017
  • Updated Input Table: cb_2017_us_county_5m

The results show zeros for population and households for counties in Alabama, Alaska, Arizona, Arkansas, California, Colorado, Connecticut, which is not correct.  The data in the Join Table is sorted alphabetically by county FP, then by state.  

 

This brings into question the validity of reports I have generated using Joins in the past.  Am I doing something wrong or is this a known issue?
