My fine tuned model is outputting gibberish

I’m having issues with getting my fine tuning to work. I have tried about 8 models and the outputs show about 5% of what I want, followed by complete gibberish. I have followed the instructions exactly, so I’m not sure what I’m doing wrong. here’s a sample prompt

“prompt”:"recipient name: **** recipient’s profile: *long profile information section sender name: **** sender business name: **** sender role: **** product name: ***** product tagline: **** product description: **** product benefits: ***** call to action: **** instructions: ***** sender message: **** "

“completion”:" *** full message **** END"}

ever have any luck with this? I observed this myself
