I tested the code that you pasted locally with the latest version and it worked  properly at my side. Would you please clarify the exact version of RadControls used and the browser used when observing this issue?

You can also refer to this help article where most of the known troubleshooting issues are listed.

Hope this will be helpful.

All the best,
