3 doctors agree

In brief: Not all removed

The leep excision must have left some dysplastic cell behind.
This is not a rare situation even when the margins appear negative under the microscope (5-10%). A repeat colonoscopy with biopsies and sampling the canal is a good idea. A second leep may be needed.
