Hi,
I have encountered a similar but different issue, The highlighted edges weren’t able to bevel by adjusting the bevel weight through transform. The ctrl+B works for all.
While there doesn’t seem like to be an angle between ‘top and bottom’ Faces like mentioned above.

here’s the link to the file: https://drive.google.com/file/d/1CmVRIAxvYAWT–DYZtE5hIFzY-_0A1SA/view
thanks!
