No way to fix it, and some of the sequence decisions there seem awfully dumb to me. 
Paragon City Search And Rescue
The Mentor Project
That would drive me nuts.
IIRC, the powers within each categories are listed in the order you got them, and the categories are listed in the order you got access to them. Therefore, you have two possible solutions:
1> Don't slot any sets until you've picked all the Pools and Epics you plan on taking.
2> Respec. You slot the sets after you pick powers, so you've effectively just done #1.
I've just got the first epic power on my lvl 41 troller... but it's listed after all my set bonuse on power description -.-' and that's not good to see -.-'
Isnt there a way to fix that?
I dont like to see that long list of bonus being shown before my epic powers :/
This is never happened with my others heroes (probably because i usually pick up set when i've laready reached lvl 50 and already choosen all my epic)
