When importing content into a new Canvas page I have used the "Create Substitution Dates" function. I've set my original due dates for Sunday and would like to move them forward in time to a future day of the week. e.g. Sunday (9/30) to Thursday (10/4). However, in practice it seems like dates are moving backward in time. e.g. Sunday (9/30) to Thursday (9/27). Can someone confirm how that function works?
