Old tickets randomly reappearing on Expo KDS

[alexhkelly1]

I'm having an issue where five to ten old, sold tickets will periodically reappear on the Expo KDS screen. Most of the time, the tickets are around 5 hours old; and there is usually a common item across all the checks. That common item could be something different each time, though. Fortunately, these checks never fired to the Prep Stations again, but it's a big inconvenience for Expo.

For example, there were 5 checks that reappeared almost 5 hours after they were originally fired. Each check had multiple items, but there was a Cobb salad on each check. 

Another time, 4 checks reappeared 5 hours later and each one had a BBQ Burger as the common item. 

Has anyone else had this happen? What did you do to stop this from continuing to happen?

Is the timer on the tickets hours old as well?

Ah! The expert is here. What could be the issue here?

Yes, the timer still shows its original Fire time. 

I know fulfillment can be affected if an order is modified, split, or the dining option was changed, but it would show up as Recalled. None of these checks say Recalled, though.

You mentioned you tried clearing cache, have you tried any of the other typical troubleshooting steps like restarts, resync orders, or resync all data? Is this happening daily? Are you still seeing the patterns you mentioned previously with common item on all tickets or was that just a coincidence?

I've tried all of those steps, with no change. Still multiple daily occurrences, still with a common item. It has ranged from 1 to 3 checks during the slow part of an afternoon, up to 14 checks all at once during a busy brunch this last Sunday.
