Fine-tuned model having long (and strange) conversations with itself after uploading new dataset!

Hey, so I spent the day testing out how to fine-tune a model, and finally managed to get everything running (or so I thought) through Terminal. When I test the new fine-tuned model in Playground, ChatGPT goes on very long rants about strange topics.

Any ides what could be causing this?

Thanks!
