Alternative solution:
Do not use the Sort/Break feature in the report. Instead, create a query of records for the report.
- In the query, select the Sort tab.
- Sort by Solicitor Name field
- Save and close the query
- Open the report parameter file
- On the General tab, click Include...>Selected records, and include the query
- Select the Format tab and highlight Sort/Break on the left
- Remove any sort fields
- Mark Sort by query order
