Hey neetu,

I'm sorry that you're still facing that issue.

Without a test case, it isn't easy to reproduce and assist you with this. If you could assemble a CodePen or something similar, as it's described here https://www.bryntum.com/forum/viewtopic.php?f=1&t=772

If you could reproduce on one of or demos, os customize one of them to match your environment and them provide some instructions to reproduce that, it would be helpful as well.
