I'm going to point you to the following post, it has most of what I would have to say about this already in it: https://www.speedrun.com/re2remake/thread/tvuy6

Some things I'll add, submitting duplicate runs only slows things down. The reason your resubmitted run was rejected quickly and your other run is still in queue is that when you submitted your run again it was placed in the exact same spot in queue, which made it easy to see a duplicate. Your run is fairly close to being looked at, based on it's location in queue. As I said in the other post, we ask for patience while we get this mass of submissions taken care of as quickly as we can. We promise that all runs will be gotten to as fast as we are able to do so.

Be patient. Continue doing your runs and your submitted run will be verified in time. Do as I did and try to ignore you submitted a run and the leader boards. I had to unfollow the game.
