Hello! I am making a resource pack, and I am having a bit of trouble with the splashes.

The splashes work fine most of the time, however, whenever the splash on the first row is displayed, a weird box symbol with letters appears before it.



Here is the splashes.txt:

BOX
Shorah, stranger!
Waffle irons!
Myst!
Riven!
Tomahna, Edanna, Amateria, Voltaic, Narayan!
Releeshahn!
Cho?
Linking Books!

Could someone help me with this? is there a way to not have the symbol appear? Please respond.
