Chamfer

[hhp.dk]

What is happening with chamfering multible edges with uneven sides (angle and distance)?

Maybe some kind of origin issue?!?!

See video.

It is a bug that's been in fusion since many years:

Not everyone face this (I don't). I suggest you 2 things:

1. Use distance-distance chamfer.

2. If you are facing problem calculating the distance, use sweep cut.
