Whenever i type something or delete something on replit it ltes me do it for a second and then it goes back to how it origanally is

this here goes straight back to how it was originally right after i click a button other than a letter or a number so if I click the spacebar control anything it goes straight back like I am going back in time and I really need help fixing this because I obviously cant do anything. Please help this has been happening for the past few days and nothing will help.I am currently on a school chrome book also.
