It was probably submitted without a panel title, which causes it not to be listed; this is a known issue, but we're not likely to release any more versions in the 1.x line of OCS as we'll be releasing OCS 2.0 soon. You'll have to correct this in the database, either by making the presentation a single presentation or by adding a panel title to it. If necessary, I can provide further instructions.
