I'm experiencing an issue with the filtering and sorting functions in a Kendo Grid. This problem seems to occur with the latest version of Kendo UI for Angular in combination with Angular 18.

I have created a sample project on StackBlitz where the issue can be reproduced: StackBlitz Project.

In the example, you can see that the filtering and sorting capabilities are enabled. However, both filtering and sorting do not seem to work correctly.

Here is a relevant code snippet:

<kendo-grid [data]="gridData" [selectable]="selectableSettings" [navigable]="true" [height]="300" filterable="menu, row" [sortable]="true">
    <kendo-grid-column field="ProductName" title="Product Name"></kendo-grid-column>
    <kendo-grid-column field="UnitsInStock" title="Units In Stock"></kendo-grid-column>
    <kendo-grid-column field="UnitsOnOrder" title="Units On Order"></kendo-grid-column>
    <kendo-grid-column field="ReorderLevel" title="Reorder Level"></kendo-grid-column>
</kendo-grid>

What I have tried:

1. I checked that the correct versions of Kendo UI and Angular are installed.
2. I tried different settings for the filtering and sorting capabilities.
3. I reviewed the Kendo UI documentation to ensure I didn't miss anything.

Current behavior:

• Filtering: When I try to filter, the results are not updated correctly.
• Sorting: Sorting does not seem to produce the correct order.

Expected behavior:

• The grid should correctly filter and sort based on the column values.

Am I doing something wrong, or does this seem to be an issue with the Kendo UI framework? Any suggestions or solutions are welcome!

Thanks in advance for the help!
