Manage traning runs pagination won't allow you to change back from 100 back to 10.
It's hard to say when or how it happened as I think it's been fine in the past, but I've been notified one of our admins was unable to change pagination from 10 to 100, the request has been corrected, and sending all 100, but JS won't work. I've tried myself, but I already had my pagination on 100, and I was unable to change it back to 10. The network requests were showing 100, as on the screenshot.
