Recenty received Adobe Acrobat Pro DC, issues with Stamp Created for Adobe Pro XI used which would update for current time and date. Worked in Pro Fine, not working in DC, how do you correct?

The stamp doesn't update to the correct date and time.  It's static, say I try to stamp today and now, the stamp will show the date and time from a week ago and the same time.  The problem was listed when the comment posted: "The stamp needs to show the current date and time when the stamp is applied within the stamp, such as the standard "Reviewed" Dynamic Stamp in DC".  The "Reviewed Dynamic Stamp" was used as an example so you would know what date and time I expected to see when applying our created stamp.  Thanks.
