Hello,

My apologize for this the inconvenience.
Have you try the WebCombo latest hotfix?
If no, please try to update the WebCombo to the latest hotfix. Then let me know if the issue still persists or not.
If yes, Would you mind to tell me, step-by-step how to reproduce your issue?
Or could you create a simple runnable project that replicates this issue, so that I can investigate the issue from my end?

Thank you.
