Yep… Many, if not most of the fillet edge failures are due to the fillet needing to end past the far edge of the face attached to the selected edge… I would say this likely falls into that category even though it is not strictly past -Pascal

FilletEdge appears to work for this producing the same fillet for both objects unless I’m going crazy. What is it you expect to happen here? Do you want some of the new faces to merge?
