Are Substitution Tables functioning in TM2023.2.3?

Hi! I’ve been trying to apply a substitution table to a model from Revit, but no matter what I do, no materials change when the model is imported. I’ll give a breakdown of my steps as well as a screenshot from my CSV (which is saved as UTF-8).

  1. Open model in Revit (from Autodesk Construction Cloud)
  2. Revit > View Tab > Twinmotion dropdown on ribbon > Open in Twinmotion
  3. Check parameters and make sure ‘Enable Substitution’ is checked
  4. Select Substitution Table file
  5. Confirm and Import
  6. Observe no changes to model’s materials

This is a screenshot from the CSV. I’ve followed the sample perfectly as far as I see, so I’m not exactly sure what I’m doing wrong here. Thanks in advance for any help.
