Problem with Steps

I am using the Blazor Steps with each RadzenStepsItem having its own container. It worked well until I added an eventcallback and now when I click on a disabled step, it throws a null reference exception. (presumably because the callback is null???) If I remove the assignment to the callback, it works fine again.
Also if I remove the "disabled" from the stepsItem it works fine.
Any idea how I can fix this? I tried setting the parameter in the method to have a assigned value of default value of null, but this didn't help.

Can you post the exception stack trace?

Updating to 2.6.0 seems to have fixed this issue, thanks
