As for the OP, try the housing with some alloy 4mm caps to determine if it's bad.
The cap is the right size. It’s a 4mm cap. It’s distorted a bit from curve of the cable. The problem isn’t with the ferrule, however. I’ve seen this on a number of different cable housings with a variety of different ferrules.
