After upgrading from One Identity Manager v9 to v10, the custom bitmask (multi-select) columns on the Person table are not displayed in Manager.
The columns have HasBitMaskConfig = TRUE set correctly, and the bitmask position entries exist in QBMColumnBitMaskConfig, but the UI does not render them at all.

The issue effects both the Manager Fat Client and the Manager Web portal.
This has been acknowledged as Product Defect #724271 in v10.
There is no workaround for this issue currently possible.
The Engineering team have opened the Product Defect 724271 to resolve this issue.
