I added two custom fields to one of our field configurations: Start Date and Completed Date (both date pickers). When I edit an issue, those fields are automatically populated with today's date so when I click the Update button, those fields get populated, they get set. Even if I try deleting the values, they get reset. Going to the history of the issue, I can see it shows that I removed the values and then immediately those values are set again.
I double checked the configuration of these fields and verified there isn't a default value set and the "Use the current date as the default" checkbox is unchecked? Any ideas as to why this happening?
