Your HighLevel (GoHighLevel) CSV import reports error 1011, Duplicate unique property value in the file. Here is what HighLevel says it means, a free checker, and the steps we follow.
What the error means
HighLevel's troubleshooting article describes error 1011 as the same unique value used multiple times within your files.

Check your CSV before you re-import
Pick the column you used as the unique value. We trim and lowercase values before comparing. Your file stays in your browser; nothing is uploaded.
How we fix it
- Open your import file and find the column you used as the unique value (for example Email, Phone or Contact ID).
- Run it through the checker above. Every repeated value is listed with its row numbers.
- For each repeat, we keep the row with the most complete, most recent information and remove or combine the others.
- HighLevel's fix: choose a different column header to act as your unique value or fix any mistakes, then re-import the files.
