System Information
Operating system: Windows-10-10.0.19043-SP0 64 Bits
Graphics card: NVIDIA GeForce GTX 1050/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 472.39

Blender Version
Broken: version: 3.0.1, branch: master, commit date: 2022-01-25 17:19, hash: dc2d180181
Worked: (newest version of Blender that worked as expected)

Short description of error
when we increase number of of order by 3 it will create 4 times (Ax+b) lines instead of 3 but the graphe show polynomial curve of third degree thought ...

what i found that the value of coeficient "A" of the forth (factor) line is the value "B" of the third (factor) line and that because when we change one of them the other also change and take the same number...

also angaint the value of coeficient "A" of the third (factor) line is the value "B" of the second (factor) line and that because when we change one of them the other also change and take the same number...
and that happen avery time we increase by one it add two line again ..

Exact steps for others to reproduce the error

add keyframe
apply generator modifier
chose factorised polynomiale
increase by 3
( bom 4 lines the issue hapen
by 4 (bom 6 lines) .....

Changed status from 'Needs Triage' to: 'Confirmed'

Simple mistake: For loop that generates the UI uses i++ instead of i+=2

i found another issue about that if we want to change representation from "factorized" to expanded the graphe change due to changing in coefficient places .... after switching to expand

@hamza-el-barmaki That is not a bug. It is just a missing feature. You can make feature requests on: https://blender.community/c/rightclickselect/
