As the title suggests, I have tried to generate stories in Spanish and they are being produced in English. All parameters have been set correctly.
Using Edge browser on MacOS 12.0.1. FWIW, I just changed the voice in read aloud to one of the Edge voices before this bug occurred.
Follow-up: I tried using Chrome, and it worked. I then tried again in Edge and it seems to be working again.
Attached is a screenshot.
