When you create an open invite with a title that has an apostrophe in it, after someone accepts it, you get a slash before the apostrophe in the email that is sent to you.
Being a software developer myself, I know the cause. It is to escape apostrophes out on the database. Just need to code it so it isn't also sent in emails. 🙂
Nothing serious, just thought it would be better sorting it out. 😉
