You did not elaborate on what kind of problem you are facing, just that you are getting different results. Here my notes based on the information you provided.
It is not a product dimension because its lines are associated with the transactions.
I created a Products dimension by picking up just all your products: 77 products.
I did not used the Product Details as products already have an id in the GettingStartedData.
This is not a dimension, you have duplicated records.
Created a Customers dimension by removing all the duplicated records: 90 customers.
The information here contains sales-cost figures per product per quarter.
It is not related to the Orders fact table in your model.
I created a dimension named Product_Sales
This table does not contain a year, only quarters, so the best we could do with is to show products sales per quater.
This table seems to contains your Orders fact table.
It exposes the ProductID and CustomerID columns which is fine.
This table does not contains measures, no orders details, the best way to get any measure is by joining with the product details on the transactions id, but, this will not fit well with the start mode.
This table contains the Quantity measure, and the OrderID.
If we look at the OrderID = 10248, it contains 3 rows with 3 different quantities. We could assume this order contains 3 products, but there is not direct way to know the products involved.
This table add very little value to the model, actually by containing year and status, there is very little we could do with these fields.
Your star schema is not properly defined, it does not allow us to put together Order-Product-Quanty, and without a measure, it will be difficult for Qlik to produce meaningful results.
