Design time error editing hierarchy grid template

Hi
I have created a new page using the hierarchy template and linked it to the child table. No others changes made.
At run time it expands and shows the child data ok
At design time if I try to edit the template I get an error


I have the latest radzen version.

Any ideas please?
Thanks

Confirmed! Fix will be released later this week.

Hello,

For my part, I have "The name 'northwindBlazorModelsNorthwindBlazorDataOrder' does not exist in the current context"

I tried to create an expandable hierarchy grid with Orders and Order details of the Northwind database.
It appears when I click on "Edit template" inside the master grid.

Thank you in advance for your feedback i possible
