What happened?

This may be more of a feature request but here's the issue:
I downloaded an InstructP2P model and follow a tutorial.
When I load the model and go to the img2img tab, there is only one CFG scale slider, whereas there should be two, one for text and one for image. I'm haven't tested with the Automatic1111 UI but in every tutorial I see, there's two sliders.

Steps to reproduce the problem

1. Load an InstructP2P model
2. Go to img2img tab
3. See only one CFG scale slider

What should have happened?

There should have been two CFG scale sliders, one for text and another for image.

What browsers do you use to access the UI ?
