Major hallucination? | Mockup app prompt generates a Strava viewer

Google AI Studio

I attempted the “Feeling lucky“ option which entered the following prompt “Create an app where I can upload my logo and see it placed on product mockups like mugs and t-shirts,“ which includes Nano Banana functionalities.
It first attempted to create it using Gemini Pro 3.1 review, which failed due to the outages happening since yesterday.
Then I switched the model to Google Gemini 2.5 which I have used in the past and worked just fine, but this time it generated something completely different and out of context: a “Strava viewer.“

On the following image, you can see what just happened:

It is kind of concerning because I have never even mentioned Strava, and I am very confused about how this mix-up may have happened.

Update:
It must have been an API error, because after canceling the first request, it didn’t log the original prompt back onto the conversation.
