Impossible shape on Tristan Top

I’m making tops for a couple people for us to all wear to the Ren Fair soon. When I went to make one for my little cousin (10, not that little anymore) the pattern generated really oddly. I had no issues when I made the pattern for myself last year.
I am not in person to take her measurements, so her mother did it for me. I assume some of the measurements were off and that’s what caused the issue? Everything else I’ve made from free sewing was for myself or husband and I took the measurements and everything went great with no issue, so I don’t have experience troubleshooting! I didn’t know if anyone would be able to suggest which measurements I should have her double check

It looks like the vertical edge on the left side of piece 1 may have got a negative length.
Is it possible that your measurement set contains the 10-year-old’s HPS to waist front | FreeSewing and an adult’s HPS to bust | FreeSewing ?

I agree that you should look at the vertical measurements, especially HPS to Waist Front if the rest of the pattern parts look okay.

I am able to generate a Tristan Inside Front part shape similar to the problem pattern if I set HPS to Waist Front to be much shorter than HPS to Bust.

Those measurements were the issue! I thought they looked wrong when I put them in and my aunt definitely read hip to bust instead of HPS. It looks correct now. Thank you so much!
