Polluting my events screen with events I've already completed

You have the ability to distinguish between players who have 330 shards of a unit and those who don't. 

I unlocked JJB in August. Why are the gungan marquees and the JJB event polluting my events tab with events I have no incentive to play again? It's not like gameplay there was so riveting that I'd like to experience them again. Anyone remember the bug with shield generator stacks in the August JJB event? I remember because I completed the event with the bug in place. 

I already have the Finalizer and Raddus capital ships at 7 stars. Why are their fleet masteries showing up with a refreshed 24 hour timer every single day now? If I was allowed to play the bonus tier, this would be a fantastic source of SSC. Before this change was made, fleet mastery events for those ships only appeared for a day when they were scheduled during the month and I could get some SSC out of them. Now those two events are permanently stuck in my events tab even though I'm not allowed to get shards to convert into SSC from the final tier. 

Stop polluting my events tab with events I can't play.
