Maria --
Thanks for sharing the screenshot of the Tasks page. I see two custom columns in that page, which are the % Expected field and the Task Status field. I would surmise that one or both of those columns contain a formula that calculates a value. I think you will need to reach out to whomever created those two custom fields and consult with them. Ultimately, there is nothing I can do to help you wish this issue. Sorry, but hope this helps.
