Possible conflict with LiveComposer, [app_confirmation] not showing up

Dear support,
I recently buy a subscription in order to test appointment+.

Appointment+ stops working on our test with Live Composer editor (from codecanyon). The calendar is ok but we can't display the confirmation form because also the green box in calendar is not clickable (nothing happened when clicking).
If live composer is disabled the calendar return to be clickable and the confirmation form appears.

Our test installation is here:

Can you guide us to solve this conflict? We have no idea how to fix it, is it a ajax issue?
We need both plugins to be active on our website.

Thanks in advance for helping us

Regards,
Marco
