OCS Scheduler Order Changes

We have scheduled presentations in four rooms and time blocks. When the Conference Schedule is displayed the presentations are in seemingly random order. I have checked several tables including rooms, room_settings, time_blocks, time_block_settings and published_papers. All seem to be consistent with what was set in the Scheduler. In the published_papers table there is a variable called seq.

I would like to reorder the list in each time block to group the presentations by room. The order displayed does not seem to coincide with the seq, paper_id or pub_id variables.

We are running OCS

Thanks for your help!!!
