It looks like the license keys are not properly registered in your application.
If you are using Syncfusion assembliesuget packages from the installer or from nuget.org , you should generate and register the corresponding version and platform license key in your application to avoid the trial license warning.
Note: If you’ve upgraded both the license key and assembliesuget packages, could you please try cleaning your project, deleting the bin\obj folders and rebuild your application, then check whether it resolves the issue?
Please follow the below kb article to know more information on removing the license warning message.
