Rededitor Association Help

What can i delete from my personal reditor roster to make room for more jerseys? I'm using this roster for association only. I tried deleting the retro teams, but it causes the roster to crash. Any ideas?

use the clone feature. you may need to pay another buck or two for that feature though.

I'm not talking about that, but thanx. I have full reditor and my stats at the bottom right read 6710.7/11217/0. I'm not entirely sure what they mean, however, the zero makes me think im running out or am out of room already. What can i delete without having the game crash? Like can i delete the retro teams?? If so how because when I try it causes the roster to crash.
