Tract 55117010501 is a 2010 census tract. 2010 census tracts are used in 2010 census data and in ACS data release years 2010 through 2019. The 2017-2021 5-year ACS data use 2020 census tracts.
It sounds like you might have joined tract data from the 2017-2021 5-year ACS to a shapefile representing 2010 census tracts. This would result in ‘empty’ data for any 2010 census tract whose ID doesn’t match a 2020 census tract.
To map 2017-2021 ACS tract data, you could use a 2021 tract shapefile. If you’d like to do direct comparisons of tract data from before and after the 2010-2020 definition changes in tracts, you could use NHGIS crosswalks to produce geographically standardized estimates for either 2010 tracts or 2020 tracts.
