so we have a strange problem. In some of our service articles we added a custom date field. But no matter what our customers put in there it will always be empty. They have to do the extra step and go into the freshly created ticket and change the date in this field again for it to save the put in date.
This is how we setup the field
After the ticket is created and a date is properly set during creation (I supervised it one time in case of user error on our customers side) it will show like in the picture below.
