Re-subscriber message and button text slash

A couple of things I’m hoping we can do. I’d like to not show a resubscriber message at all even if we are updating their profile. I have them going into an audience that we use for our courses. If they opt-in to be put on a waitlist for a future course and they already have purchased a course before, they don’t need to know that we are updating their profile (tags) as they won’t even know what that means. I think this will confuse them. Is there a way to not show anything if they are already in the audience?

Second item is that I have the button text “I CAN’T WAIT!” but every time I update the form, it creates a backslash right before the apostrophe. If I change anything on the form and update it again, it continues to add backslashes. No matter what I do, it continues to add them. Can this be fixed? I don’t want to have to spell out “can’t”.
