I'm working in Jira cloud, and set up a pretty simple project to track investigations of service issues for our customer service team. The project has one issue type, with three statuses (to-do, in progress, done).
The project has a pretty default agile board, with one column per status. No other filters on the board.
Started entering issues, and when I got to the 27th one (SIRI-27) the issues don't show up on the board any more. Doesn't matter whether they any of the three statuses, they simply don't show up. Search finds the issues just fine.
What am I missing on setup?
