Multi-Select freezes

Hi,
I'm using the Multi-select checkbox, but when I select more than one checkbox the whole thing freezes. I'm not too sure where to look for any thrown error.

Check Radzen output pane and browser console for errors.

On selection of a checkbox I get:

Based on a previous discuss this datafield is of type List

I’m not sure what is causing this issue. If you have a Radzen subscription you can send your project to info@radzen.com.
