Double Wall round collars are not cut out nor reported in Fabrication CAMDUCT

[moustafa.eldysouky6Y6TY]

Patterns such as CID 29 and CID 8 have been taken off in Autodesk® Fabrication CAMduct™, a Double Wall has been applied and the inner collar appears in the 3D preview as expected, the inner collar development is missed though nor it shows up in any report.

I have tried using Version 2020.0.0.F (30) and Version 2021.0.0.F (31) but no use.
