Confirming appointments resets provider schedules


I’m using appointments+ and buddypress to schedule online lessons. When a provider goes to the confirm appointments section of their buddypress profile ( in members/[user name]/appointments/my-appointments/ ), whenever they confirm an appointment, it resets their schedule – i.e. the schedule they set in members/[user name]/appointments/appointment-settings/ is reset to available on no days at no hours. Is there a way to allow service providers to confirm appointments using their buddypress appointments page without resetting their schedules? Thanks!
