comfyanonymous/flux_dev_scaled_fp8_test with flux-redux gives black images.

### Expected Behavior

Make normal image.

### Actual Behavior

Make black image.

### Steps to Reproduce

1. use flux redux
2. use comfyanonymous/flux_dev_scaled_fp8_test model

I use normal nothing-special workflow with flux-redux. As soon as I switch diffusion model to downloaded from hf comfyanonymous/flux_dev_scaled_fp8_test from regular flux-dev image generated becomes black solid. Also GGUF model works ok. Again, issue shows only when using flux-redux. When I bypass group with redux nodes, image is correct.


### Debug Logs
