I've observed numerous instances when the column analysis and reports display conflicting results. Some results will be identical and some will differ.
In one instance, looking at the column analysis results, I see that one field has 1 conforming format and 1 violating format. In the Column Profile > Post Review report, it shows 2 conforming format and 0 violating format for the same field.
In another instance, the column analysis shows a field with 1,000 distinct conforming formats and 1 violating format. In the Column Profile > Post Review report, it shows 1 conforming format and 0 violating format for the same field.
I've confirmed that the analysis and report use the same data source.
