The line spacing in Motion 5 doesn't work anymore

I am trying to create a title in Motion 5. After I had typed my text, increased the size, adjust the vertical alignment, I wanted to decrease the line spacing so the two line text will be touching. First time doing this, the line spacing worked. When I went to readjust it, it quit. I had rebooted the Motion 5 and still the line spacing doesn't work. I then restarted the computer and reopened Motion 5 and repeat the process up until the line spacing, it still doesn't work. Don't know what had happened. Any suggestions would be appreciated.
