Under certain circumstances, the paging on Monitoring/Triggers can result in a message like "Displaying 3 to 2 of 2 found" and an empty table.
It seems to occur when the number of results exactly matches the paging limit.
- Set a rather low paging limit, like 5
- Filter for enough events to fit two pages
- Navigate to the second page
- Adjust the filter to exactly return as many results as your paging limit is set to
- Witness what I described above
The version is 2.2.5. I found nothing suspicious in the later 2.2 changelogs.
