Comments are getting cleared on Button Action

Hello Gurus,

I have created a Form and Added comments element on the Form to enter the user comments.

when I press the button (Action), comments are getting cleared in Quality system and it is working fine in Development system.

On button action, I am just reading the data entered on the form to send the information to Backend using oData call. here i have not kept any logic to clear the form data.

Any ideas, What could be the reason to clear the comments?

Thanks

Shyam
