Subtitles Glitch

I was flying along the world and the subtitles kept saying 'minecart rolls'. I wasn't using a minecart at all and I was flying quite high up from the ground so there wasn't much sound anyway.

What I expected to happen was...:
There to be no subtitle saying 'minecart rolls' because I wasn't using one.

What actually happened was...:
There was a subtitle saying 'minecart rolls' even know I wasn't using one.

Steps to Reproduce:
1. Put subtitles on.
2. Just kinda, wait I guess haha
3. ...
