HELP ME Why are the ratios different

I noticed a weird thing drawing harmonics.
Certain ratios are completely different in tradingview if you use the Cypher tool vs. the XABCD tool.

All points on the image are identical when drawn (I moved them apart to show what I mean)

Specifically AC ratio is way different. And it makes a big difference to the validity of the pattern!!!!

Can someone explain which is correct and why they are different?!
