Completed cases reappear as empty on tablet

We have a survey with a preloaded sample. We assign cases to enumerators. When those cases are completed and sent off from the tablets, the data appears as compete in the headquarters for those cases, as it should. However, those same cases that were completed, reappear on the tablets of the enumerators to whom they were initially assigned, and appear to be empty, which is confusing the enumerators. Could you please help resolve this issue ?

Please, reproduce the issue on the public demo server (please use hypothetical data as this is publicly accessible), then send information to the support email using the green checklist.
