I had this issue too, and the problem was having Clamp Overlap as Martin Bergwerf says. Thanks Martin!
However, what I don’t understand is that when I had Clamp Overlap enabled, and only selected one edge of the grille (only the two outer grilles, and specifically the edges towards the back on them caused issues), then modifying the Bevel Weight for that edge, impacted all other edges with weights (e.g the buttons that were set earlier), but not the selected edge. Reading the documentation for Clamp Overlap does not explain why this would happen. I’m using Blender 4.2.
There were also other edges outside the grille that would cause this to happen too.
