printToSprite("1") displays blank sprite

[Exiled350]

Using an ESP32-WROOM-32D, Visual Studio Code, ST7789V SPI display. When calling printToSprite() anything with just the number one "1" will display a blank sprite. anything else works, numbers, letters, a "1" with another character. Both printToSprite("1") and printToSprite((String) (x)) where x == 1. The sprite is generated and appears to be the correct size, it's just blank.
