Dashboards

I've created a dashboard for my team. One that focuses on what the team is currently doing (filers: on track and doing and completed). Created a widget for each team member with these filters and also created a widget with only intake triage so that I can move tasks from intake and put them in each individual team members widget, but when I move from intake or from other team members widgets into a different team members widget then the date of the task changes. I don't know why this is happening or how to rectify it. Is there anyway to solve this issues? Help is greatly appreciated.
