Object reference no longer working on Firefly 4?

So, I've used the reference image technique in the previous version of FF, always to some degree of success.
Now, in FF4, the process is no longer returning the same kind of results.
My process is:
1. Create prompt with initial base idea ie: cube made of glass, dark background, light refraction (using presets Hyper realistic, Beautiful, Futuristic, Studio Light), and Generate.
2. Pick up the most adequate result and use it as Style Reference
3. Upload my own Structure reference. Generate.
4. Results are basically variations of the Style reference, totally ignoring the Structure reference.

I play with the Strength sliders, but to no avail.
What happened? Why isn't this working anymore?
