Hi, @ebonyjean!
The default field size in Aggregate is set to 255. Users can add an odk:length attribute in the <bind> elements to increase the size of fields to fit their data. This is recommended in geo fields like the ones you're using.
More info at https://docs.opendatakit.org/aggregate-field-length and in the warning at https://docs.opendatakit.org/form-question-types/#geotrace-widget
