One week ago, I purchased the new Amelia Pro release, because it promised to be capable of managing resources and service packages.
In fact, in Amelia's changelog it is stated:

Version 5.6 (17.11.2022)
Feature: Limit appointments, packages, and events per customer

Version 6.0 (22.12.2022)
Feature: RESOURCES – Ability to create shared or single resources that limit the bookings, available only in Pro and Developer licenses

My problem with the Amelia plugin
(Environment: Apache | MySql 5.6.5 | PHP 7.4.3.0 | SSL | Wordpress 6.1.1 | Plugins: only Amelia Pro 6.1)

I've to setup a package of 5 single lessons hours for a service that can be booked by a customer only 1 time per week. For this purpose I create in Amelia a very simple configuration:

CATEGORY

• Name: Pole Gym

RESOURCE

• Name: Pole classroom max 10 students
• Quantity: 10
• Services: 1 hour Pole Lesson - Limit 1 per week
• Employee: Pole teacher

SERVICE

• Name: 1 hour Pole Lesson - Limit 1 per week
• Category: Pole Gym
• Employee: Pole Teacher
• Limit appointments per customer: 
  
  • Number: 1
    Time frame: week
    Period:1
    Time period is calculated from: Appointment date and time.
• Duration: 1 hour
  • Minimum capacity: 1
    Maximum capacity: 10;

EMPLOYEE

• First + Last Name: Pole Teacher
• Assigned Services:
  • Pole Gym
    • 1 hour Pole Lesson - Limit 1 per week
    • Capacity: 1 to 10
• Work Hours: Thuesday and Thursday from 15:00 to 16:30

PACKAGE

• Name: Package 5 x 1 hour Pole lesson
• Duration: until February 28 2023
• Services: 1 hour Pole Lesson - Limit 1 per week
  • Number of Appointments: 5

I assigned the package to a customer but, despite of the above settings, the same customer in wp frontend is able to book more than 1 appointment for week.

The problem remains, even when I don't use resources.
Later, I encountered the same problem in your demo site!

Are my settings wrong?
Should I adjust the settings in a different way?
Is there a bug in your plugin?

If you want, I can provide you a WP-admin user for my pre-production site.

If the problem persists I would like to be refunded.

Thanks in advance for your help.
