Based on the review of the provided README.md and task.json files, here are some identified issues:

1. **Mismatch in task description between README.md and task.json:**
   - **Issue**: "Task name mismatch"
   - **Evidence**: In `README.md`, the task is described as "Data Wrangling Problems" focusing on "reduceName-9" from domain 'names' with prompt style 'statement'. However, in `task.json`, the task is named "reduceName-9_names_2".
   - **Description**: There is a discrepancy between the name and description of the task between the two documents. The README.md does not specify the "_names_2" suffix that appears in task.json, which could lead to confusion about the exact task identification.

2. **Incomplete email addresses in README.md:**
   - **Issue**: "Incomplete email addresses"
   - **Evidence**: The email addresses listed for the authors in the README.md file are incomplete, showing placeholders like `{gonjailo,liconoc,cferri,jorallo,fmartinez,mramirez}@dsic.upv.es` instead of individual complete addresses.
   - **Description**: The formatting of the email addresses in the README.md is unconventional and might lead to difficulties in contacting the authors directly. Normally, each individual should have a fully specified email address.

These issues highlight discrepancies in task naming and lack of clarity in communication details which can affect the usability of the dataset for external reviewers or users.
