Try each of the following steps in order until the issue is resolved:

 
       
    • Ensure the correct queries were selected for the merge.
     
    • Ensure the queries selected for the merge have the correct query type. For example, if you want to select constituents based on giving, the queries should have a query type of Constituent instead of Gift.
     
    • Check the criteria of each query to be merged and ensure they are correct. Select the Results tab to ensure the correct records are selected in the queries.
       
    • Refresh each query if it is static.
