Why are these flanges not symmetrical?

I have another model with similar geometry and the same problem. I dumbed it down to the simplest feature tree I could. The modeling on each side is exactly the same, but the flanges resolve differently. What gives?

    @david_buss079 Thank you for this example. I've written an issue to address it. If you can share more examples - it would help.

    @lana Is this issue resolved? I can't share the other example unfortunately

    @lana friendly ping! have tried modeling this in several different ways now

    putting a flange on one side and mirroring the feature still leads to the same asymmetry (which is strange, considering that makes it not a mirror)

    have tried modeling from the ground up as a thickened sketch, then manual flanges. no luck

    will there be a fix for this?

    We are working on the fix. Sorry for the inconvenience. In meantime you can address this with cutting out the relief manually. See Corner→sketch in flat,→cut sequence here https://cad.onshape.com/documents/824429367ca211c144723523/w/cd83d2c46380e5a01450020c/e/f182021319695d08541a983a
