WP appointment E-mail macro values

Hi there,

We've bought appointments plugin and it looks great. The issue we have currently is with filling up the content of confirmation email with custom fields.

For instance we created a custom field "Client Mobile" and your plugins says:
"E-mail macro: FIELD_CLIENTMOBILE This is the placeholder you can use in your emails."

So we used FIELD_CLIENTMOBILE in our confirmation email but instead what it does is filling up CLIENT part with a client name and puts it between FIELD_ and MOBILE.

Can you tell me if that's not working properly or it never meant to be working?
