the /title command no longer wraps text to next line

So I have a minigame world that I been working on for a couple years and theres about 50 games. Each game I used the /title @p title and the /title @p subtitle command so that it feels a lot more welcoming. But recently I noticed the text on the titles no longer fills the screen, instead it just goes on one line and goes on and off the screen. Please change it back, I really don't want to adjust 100 /title command blocks.
