Edge store and forward not flushing records

On Ignition Edge (I’m using 8.1.4), for some reason the Store and Forward web page status screen isn’t updating correctly. It continuously shows the same large amount of records needing to be sync’ed. There are no syncing errors in the log file and new data is syncing correctly to the central gateway. These pending records were accumulated during a network disconnect…and when re-connected, we did see data get pushed (although the large number of records didn’t change). The file default.idb doesn’t seem to reduce in size either. Any ideas why this would happen?
