Sometimes all active records do not show up on the CORE screens.
When active records are missing from the lists, it means that filters have been applied. The Reset Filters option allows you, the logged-in user, to clear out all the screen filters in one go. To reset filters:
- Open the User Preferences screen from the company menu.
- On the General panel, click Reset Filters and confirm when prompted to clear out all screen filters.
- Click Save.
If this still does not resolve the issue, this might be a sorting issue. Click on any column header to sort the activities and it should display them accordingly.
