Unity Asset Store just rejected 2 of my submission

So, I am trying to get some stuff up on Unity Asset Store to see the market data, but they keep rejecting me, so far I have submitted 2 product

1. GUI button layout
- So I created 10 unique GUI button skin and try to sell for $2, Unity Asset Store said "they are not interested"

2. Multiplayer Space Shooter
- So I try to sell my completed project "multiplayer space shooter" on Unity Asset Store, they said " they decided not to publish" without giving me any reason why

So sad, I would just have to find some alternative market to try sell my stuff
