Hi thowfik, 
 
Greetings from Syncfusion support. 
 
We checked the reported issue in our end. We can able to reproduce the reported issue in our end. The cause of the issue is you have set the value as string or number. But in multiselect component value property is array of string | number | Boolean.  So you need to set the value as array format. Please refer the below code, 
 
this.multiselectObj.value = ['Game6']; 
 
we created a sample based on your requirement. Please find the sample here: https://stackblitz.com/edit/angular-vqv7kb-dtm2xi?file=app.component.html  
 
to know more about our value property. Please refer the below documentation. 
 
Regards, 
Sureshkumar P
