spellcheck issue on square terminal

[Janepell]

We have a square terminal at our gallery. We have to write descriptions for every item sold. Just above the keyboard, as you start to type, it guesses what words you're typing, like an autocorrect but it doesn't behave as an autocorrect. The words it's putting up there are completely different than what you're typing.

For example, trying to type in "lavender," the suggested words are "leaf, he, piece, large."

This really slows down transactions. Any ideas what is going on?
