I have the following suggestions for this case:
1. Try upgrading to the latest version of the controls, if not already in use.
2. You can open a formal support ticket to send us a very basic runnable sample demonstrating your specific configuration and the issue you are facing. This will enable us to reproduce the exact problem locally on our side to further investigate and debug it. And then we will send you back more precise and accurate solutions, tailored specifically for your project.
