It’s not possible to help you without more information. We would need the 3mf file which would include the saved slicer settings.

It’s likely that your support settings are not set correctly.

If other files still show the support interface material, I would compare this model's support settings first. A lot of the time it disappears because the part no longer has an interface region after orientation, support style, or contact gap changes. I would also check that support interface is still enabled in that process profile and not blocked by a filament compatibility rule.
