Empty Output When `use_mask_input_as_output_without_sam` is False

Hello,

I am trying to prompt SAM2 with masks, and I would like the model to refine these prompts based on the adjacent frames and not just return the prompts in the output. My understanding is that the `use_mask_input_as_output_without_sam` flag controls this.

However, when I change its value to False from its default value of True, I observe zero/empty masks in all of the outputs. Has anyone encountered a problem similar to this or know if there are other flags that can be useful?

Thank you!
