Service Name is not showing correctly after 1.5.5 Update

I have 275 services setup each has its own Service name.

Example
Repair Screen Touch Assembly IPad Air 2 White

Using short code:
[app_monthly_schedule worker="3" service="274"][app_pagination month="1" step="1"][app_confirmation title="Check your details" button_text="Click Here to Complete"]

Since version 1.5.5
When I now make an appointment, and select the time the Appointments Confirmation screen is showing the same Service Name related to service #158
“Repair Screen Touch Assembly IPad Air 1 White” for all services.

This occurred after creating 3 new services.
Product “Repair Screen Touch Assembly IPad Air 1 White” #158 was duplicated and used to create the following 3 new products:
1. Repair Screen Touch Assembly IPad Air 1 Black #273
2. Repair Screen Touch Assembly IPad Air 2 White #274
3. Repair Screen Touch Assembly IPad Air 2 Black #275

The short codes have been changed in each new product, to the correct service number.

This procedure of duplicating a product worked fine prior to version 1.5.5
