Why Niantic Not make feature,that you can, delete the Nominations you withdrawn, or getting Rejected,duplicated and etc!?
Hello and Welcome,
You can use the filters to hide them?
I know we can do that,but everytime us login,we must a filter it again 
I get the sentiment, I hate seeing red, too. But I think it is valuable to have all the submissions we have made listed permanently on our contributions page.
I agree that all the submissions should remain but wouldn’t be against being able to save the current filters.
Only problem I see is that you hide Rejected. Some that where in the process disappear and you don’t realise that they have been rejected.
Wouldn’t be a problem for me but for those that nominate in larger numbers and maybe have many similar it could be.
I would love to have a foldering system so i can move things into folders or “buckets” to categorize them.
