The recent reminder on the SMB1 forum aptly applies to SMB2J as well. To copy the text of Tecate's forum post:

"Hi all,

Due to a rash of submissions lately that did not show a reset to the title screen prior to the run, we're posting this reminder to please show the reset to the title screen in your run submissions. If there is no reset to the title screen, we'll simply reject the run with a note to re-submit with the reset to the title screen shown.

This is just one of many mechanisms and rules we have in place to make sure all runs are valid.

Thanks!"
