Had a similar problem where we ended up with a key that gave some words and some nonsense. We also had to fix it manually, and fix some of the substitutions.
If you did this, and have something legible that feels like it should be the answer but isn’t, I would recommend you double check every word and make sure there isn’t a possibility that one of the the letters could be substituted for another, and still make sense! That was our issue
