Chamfer Hole Not Working

Hello all,
Fair warning - this is probably a very simple solution, but I am stuck. I am brand new to Onshape (day 1) and I just made my first model, a fan. When adding the hole for the motor, I wanted to add a chamfer to help mitigate elephants foot on my 3d printer. For some reason, I cannot get this hole to chamfer. No errors or anything, just no chamfer, I only get the lines where the chamfer edges would be. I have tried using a subtract extrusion, an add extrusion with a boolean, about 20 different values, even fillets and holes. For some reason I just cant get the chamfer to actually stick. Can someone tell me where I went wrong?
Thank you in advance!

It's your pattern. You patterned the entier "part" and now there are 7 parts sitting on top of each other. The chamfer is working, but it's chamfering one of the 7 parts, and the 6 other parts are hiding it. If you put the chamfer before the pattern it will look as expected. Fix the pattern though, that is the root cause.0

The problem with the pattern is this round. If you suppress it, the pattern works properly with the "add" selection.0 -
The root cause seems to be Fillet 1. This is the reason you cannot Boolean the 7 parts into 1, either as a separate operation or as part of the circular pattern. The geometry does not seem happy with the "Conic" value in Fillet 1 when used with a fillet radius exactly half the diameter of the base cylinder. Just testing it out with a circular (distance) "Control" parameter makes things work...0
