Metahuman Parametric Wardrobe asset missing cloth simulation 5.8

Hi everyone! Having an issue with the new Parametric system in 5.8.

I have several assets functioning correctly and resizing properly through the parametric pipeline. I’m using route C in the documentation for parametric clothing - Custom sim mesh + render mesh as cloth assets then outfit assets.
Both the cloth assets and outfit assets show the cloth simulation working correctly in the viewport as intended.
When applied to Metahuman via character creator and creating a warddrobe asset - the item converts back to static.
Wondering if this is a limitation of the parametric system itself or if there’s something I’m missing.
Thanks!
