Slash appearing after apostrophe

[cmcswee]

Hi there,

We're using WP SMS with Contact form 7 and in the 'SMS Notification' tab under 'Send to form', we have some text that reads "Merci d'avoir choisi"...etc.

The problem is that when I click save, a backslash appears in just after the "Merci d" so the message reads "Merci d'avoir choisi"

Any time we save it, the slash increases, so after a few saves the message reads "Merci d\\\'avoir choisi" …etc.

Is there any way to stop the slashes from appearing?
