Removing a line from captions

When making my videos of historical figures, I like forthier name to be all on 1 line. Today, I was making one about Queen Elizabeth I. The cations put it as
Queen
Elizabeth
the first.

I was able to move the words around a little to make it one line and have only 1 empty line instead of 2. Now, when playing the video, a small dot pops up where there were words. I wish I could remove that font box altogether so it doesn’t generate any words or boxes for words on the video.
