From your attachment, it seems to me that the kendo theme css files are missing in your project.
Please review your project and see if they are missing. For more information refer to our documentation article
for Manual Setup
If the css files are added, check for any errors in the project and in the browser console too.
Also, I noticed that you are using a local file resource for localization.
Is this the kendo localization file
which you have saved in the project file system or it is yours?
If you could not find the root of the issue, please provide us more information about your project - css themes that you are using, scripts, libraries. Everything that will be in help. If you could send a demo project it will be better.
