Appointments+ Google Calendar schedule issue.

I am using the appointments plugin, but It seems to have an issue with daylight savings time, and or can't find the setting. Basically every appointment I schedule shows up on the google cal one hour later than scheduled.

And one more issue is when an Appointment booked, it sends 2 email, one to admin and the other to the client.
but on email 'Reply-To:' field site admin email is showings instead of WP email. And not sure if it is expected or inappropriate and the confirmation email doesn't match its settings, for example, the email confirmation that just went out just said "new appointment", it doesn't match what was set for it.
