Need advice for creating a sheet metal flange (non-rectangular)

Having difficulty in creating a flange on an interior cutout that is not "nicely" rectangular.
Onshape seams to be having a problem with wanting to put in blend reliefs during the flange creation which are confusing the issue.
The "Automatic miter" option isn't properly mitering the overlapping intersection. So I manually entered an appropriate miter angle.
Got closer to result, but the bend reliefs still appears to be an issue. Even tried making the bend radius really small.
I would welcome and ideas on how to get this to work.
Note: After the fact I will change the bend relief and to a "tear".
Comment: Given that incorporating a default bend relief while creating a flange can cause problems wouldn't it make sense to have the option to specify the blend relief type during flange creation?

Here is one way.
Step 1: Make a rectangle cutout of length and width on 3D model.
step 2:Place flange in 3D model.
step3: Cutout shape on Flat pattern.
Step 4: Use extrude and fill in the open area on Flat pattern:
