Field Validation issue in CK Editor

Hi,

I'm using the CK Editor widget for a field instead of a textarea in my application. I used the following statements for field validtion using a microflow.

$Enitity/AttributeName != empty  and  $Entity/AttributeName != ''

When im saving the form after filling the field it is working fine. But we are leaving field empty and saving the form it is showing the validation "this field is required". After that when I fill the field with some data and save the form, it is still showing the field validation("this field is required")

I also updted  the CK Editor widget with the latest version.
