That designation means size 19 ladder, ld for ladder. Perhaps none of the games have completed since this new system was set up, resulting in a blank page. That's silly.
On the tournaments page, in the ladder column, check to see if you are registered for 19.
If you are, unregister and that should solve your problem.
I am registered but there are other games in progress that belong to the new system, while those games mentioned above don't seem to belong there. I would like to stay registered only under the new system.
