how can i use firefly v4 & 5 to create as a structure?

with Adobe V3 i can draw an outline of a house for example and ask Firefly V3 to transform this in a futuristic house for example and it will do it.

with Adobe V4 and V5 if i ask the same thing it will basically create a futuristic house in the middle of the image and put my outline as a traced white outline.

Does anyone have any advise? as im worried about the day they go end of life on V3 and im unable to do it.
