Reference image falling off of search

A few days ago I was using the generative text-to-image with a reference image. After it would generate, I would select one of the 4 options that was close to what I wanted, click "show similar", and the reference image would stay as part of the next search. That was very helpful and lead to lots of great content. Currently, when clicking "show similar" the reference image falls off and disapears and the next images generated are not as close to what I was trying to create.
