Description

When all dimensions are initially collapsed ([defaultExpandState] = 'false' or not set) and first dimension has children the second dimension data does not display correctly.

• igniteui-angular version:
• browser:

Steps to reproduce

1. Run the pivot-hierarchy sample with config:

columns: [
            {
                memberName: 'AllSeller',
                memberFunction: () => 'All Sellers',
                enabled: true,
                childLevel:
                {
                    memberName: 'Seller',
                    memberFunction: (data) => data.Seller.Name,
                    enabled: true,
                },
            },
        ],
        rows: [
            {
                memberName: 'AllProduct',
                memberFunction: () => 'All Products',
                enabled: true,
                childLevel:
                {
    
                    memberName: 'Product',
                    memberFunction: (data) => data.Product.Name,
                    enabled: true
                }
            },
            {
                memberName: 'City',
                memberFunction: (data) => data.Seller.City,
                enabled: true,
            },
        ],

Result

Observe that the second dimension does not show its values.

Expected result

Should show all unique City values as rows.

Note: Works as expected if [defaultExpandState] = 'true' .

Attachments

Attach a sample if available, and screenshots, if applicable.

Also if expanded there are cases where there are multiple Cities even when expanded, but the they are not shown
