Non English language bug?

im trying to make a simple homebrew item and i got a warning message i never saw before saying if i wanted to publish the homebrew it had to be in english? But… the entire description is in english? I do have dyslexia so perhaps i misspelled something but i went over it with a fine toothed comb and keep getting the same error message? Is there maby a spelling issue its being to strict about or is this a bug 

Hats the odd thing. I did hand type that tooltip, and i still got this error
