Leash knot subtitles are not properly capitalized

The bug

The subtitle for tying a lead to a fence is 'Leash knot tied', and the subtitle for breaking a leash knot is 'Leash knot breaks'. However, the name of the entity is Leash Knot, with both words capitalized. These subtitles should capitalize 'knot' too.

How to reproduce

1. Summon a chicken, and place a fence post next to it
2. Tie the chicken to the fence, and notice the incorrect subtitle
3. Break the leash knot on the fence, and notice the incorrect subtitle
