Computer Not Taking Control of Minor Leagues

[landru22]

I was hoping someone could enlighten me. No matter what I do I can't seem to get the AI to take control of my minor leagues. Here are my Team Control Settings:

Setting Lineups/Depth/Pitching Staff -- Me
Roster Moves --- Me
Transactions --- Me
Minor League Signings/Releases --- Minor League Managers
Minor League Promotions/Demotinos --- Minor League Managers
Minor League Lineups/Depth/Pitching --- Minor League Managers
Initiate and React to Trades --- Me

Despite these settings, the AI never puts any minor leaguers on the DL, never signs any minor league free agents, and never realeses anyone. Is there a setting somewhere I am missing? BTW, I checked under each teams settings (Options and Ballpark) and for each minor league team the Roster AI -- Prevent any AI Roster Changes, is unchecked.

A little background on my league: Started with a 16 team fictional league with one level of minor leagues. After a few seasons, I added a second level of minor leagues. A few seasons after that I expanded all leagues to 20 teams.

Edit:
I just noticed that my ML team option has Prevent AI Roster Changes checked. Should that be so?

Another Edit:
Yes, changing that option (unchecking Prevent AI Roster Changes for my ML team) seems to have fixed my problem. Will have to see if the AI now makes changes to my ML team though. So far, so good.
