Welcome, @james138, but sorry!! You’ve run into a software bug, certainly not an intentional thing.
Your report is very clear and the screenshot is perfect (that “40 rabid starfish…” is a unique phrase Asana support can use to identify this occurrence specifically.
Try these troubleshooting steps (you’ve already done them, but if you do this first it might expedite with Support), then please create a support ticket: see How to contact our Support Team.
Thanks,
Larry
