Reservation note not send

Hi,

if I select a reservation in the backend and fill out the text-field "Reservation Note", check "Notify customer via email" and click on "Submit",

- the button disappers
- I have to reload the page to see the updated status of the reservation
- I do not receive an e-mail for the customer email adress i.e. I do not get any email at all (spam folder checked)
