Roster corruption?
 

We have an online league and may have found a roster corruption, a player was traded from Team A to Team B, has played for Team B for the entire current season but is still showing on Team A's 40-man roster. Have tried everything to remove him (even deleted the player) and it still lists him on the 40-man for Team A. Any transaction (waiving, releasing, etc) from there affects his status on Team B.

Has any one else encountered a scenario like this? Is there any way out of it?
