Here is what MFL replied with:
"We won't be making any more player position changes in the system, so the players will remain at their current positions. You can use the League > Setup > Players And Rosters > Change Player Position to change a player's position if your league feels there are some that should be changed. We're using the "True Positoin" concept for player position designations, which is why Robinson is a DE in our system."

It's actually better for you IMO - if you have a player you can start at DL, who is getting LB points, score for you.
