Hello community! Smartsheet is new to me, and while I find it generally helpful and easy to use, I have difficulty working with cells. When I change the project start date or finish date, the cells become blank. Although I have tried saving, closing, and restarting, the problem persists.

I have checked out the online training and forums, but have not been able to find an answer. Thanks in advance for any suggestions you may have.
