Error with grouping - timeline view events are shown in the wrong row

Hey there,

I am facing some weird issue in the scheduler.

This event is mapped to the resource "DU XX 000" as you can see in the popup.
Anyway it is shown in the timeline week in a completely other group?

Same view for just week is working fine:

Is there something I can do to fix the timeline week view?

Hey Vijay, I will prepare a sample. In my case, I have different groups in one scheduler and my users can dynamically switch between the grouping options.

Hi guys,

I finally solved my problem.

It was a css issue. 

I upgraded the material.css according to the Syncfusion.Blazor version and now it works well.

Hope it helps.
